A radiator grill 7 is disposed above the fastening flange portion 15 and the fastening screw 16.

  Moreover, as shown in FIG. 1, FIG. 2, the base material main body which laminated | stacked the edge part 12 which laminated | stacked the film material 2 for decorating on the surface to the resin base material 1 on the surface. 11 and a fixing means 4 for fixing the end portion 12 and the substrate body 11 in a state where the end portion 12 is folded back to the back surface side of the substrate body 11 by the folded portion 13. (41, 42). A fastening hole 151 is formed in the fastening flange portion 15. Here, the material of the resin base material 1 is, for example, a polyolefin resin such as PP (polypropylene) or PE (polyethylene). Moreover, the material of the film material 2 for decoration corresponds to the thermoplastic resin (for example, acrylic resin or urethane resin etc.) softened by heating.

  Moreover, as shown to Fig.2 (a), the edge part 12 and the base material main body 11 before folding back are substantially the same thickness as a whole, and both back surfaces are formed on the substantially the same surface. Further, the folded portion 13 includes a groove 131 in which the front surface side of the resin base material 1 is formed in a concave shape before the end portion 12 is folded back to the back surface side of the base body 11. The decorative film material 2 is stuck in a concave shape along the surface shape of the groove 131. By increasing the cross-sectional length of the concave portion 25 of the decorative film material 2 attached to the groove 131, the elongation of the decorative film material 2 at the time of folding can be reduced.

The resin component (front bumper) 6 includes a resin base 61 and a urethane coating portion 62 that is urethane-coated on the surface side.

  Generally, resin materials (for example, polyolefin resins such as PP (polypropylene) and PE (polyethylene)) used for general purposes have a small surface polarity and are chemically stable. Therefore, in the case of a conventional structure in which a resin base material made of the above resin material is urethane-bonded to a urethane-coated resin part, by performing frame processing, corona processing, plasma processing, etc. as pretreatment, the back surface of the resin base material It is customary to generate polar groups (mainly oxidative functional groups) on the side and chemically activate them to improve adhesion. Therefore, as shown in FIG. 4 (a), in the adhesive portion having the conventional structure, for example, a frame processing layer is formed in advance on the adhesive surface of the resin base material (PP base material), and a primer layer is formed on the frame processing layer. And form a urethane adhesive layer.

  However, the decorative film material 2 (for example, acrylic resin or urethane resin) has a higher polarity (chemically activated) than olefin resin such as PP. There is no need to perform corona treatment or plasma treatment. Therefore, as shown in FIG.4 (b), in this film decorating component 10, adhesion | attachment of the film material 2 for decorating laminated | stacked on the surface of the edge part (PP base material) 12 turned back by the base-material back surface side. An adhesive portion 5 having a primer layer 52 and a urethane adhesive layer 51 is formed on the surface.
