However, the present invention is not limited to this, and only one accordion fold 22a may be formed as shown in FIGS. 12A and 12B, or three or more accordion folds 22a may be formed. You may form continuously. When only one bellows fold 22a is formed, when the mounting position of the camera core module 23 and the board-to-board connector 24 is in the rotational direction, the above-described configuration as shown in FIGS. 13 (a) and 13 (b). When one side in the width direction of one accordion fold 22a is closed and the other side is opened, the rotation direction can be followed to some extent. Even when the mounting position of the camera core module 23 and the board-to-board connector 24 is shifted in the X-axis direction, as shown in FIGS. The fold line 22a can follow the X-axis direction to some extent.

  Further, the fold 12c of one mountain fold of FIG. 5 (a) and FIG. 5 (b) described above is formed by a predetermined length in the Y-axis direction (direction perpendicular to the X-axis direction). If the folds 12d and 12d in the width direction of the flexible portion 22 are provided as shown in FIG. 15A and FIG. 15B, it is much more than in the case of FIG. 5A and FIG. As shown in FIG. 16, it is possible to follow the rotation direction. Further, when the mounting position of the camera core module 23 and the board-to-board connector 24 is shifted in the X-axis direction, the deviation in the X-axis direction is greatly increased as shown in FIGS. Can be followed.

  That is, valley folds 12d in the X-axis direction are formed on both sides in the longitudinal direction of the fold folds 12c only in the Y-axis direction, and valley folds in the X-axis direction are formed from the start and end points of the folds 12c in the Y-axis direction. Each fold 12e is formed in a diagonal direction reaching the starting point and the ending point of the fold 12d.
