Abstract

PURPOSE:To produce a cubic display body having a stepped part at the surface and capable of being formed easily at a low cost by means of electroforming. CONSTITUTION:The display body 3 of this invention has a primary electroformed part 7 and a secondary electroformed part 11 covering the side face and the top face of the primary electroformed part 7 and having practically uniform thickness. The display body 3 can be produced by coating a metallic substrate 1 with a first mask having a first notched part, forming the primary electroformed part 7 in the first notched part by means of electroforming, removing the first mask, coating the metallic substrate 1 with a second mask 10 having a second notched part with an area larger than that of the first notched part in a manner to enclose the primary electroformed part 7, forming the secondary electroformed part 11 in the second notched part of the second mask 10, removing the second mask 10, and then removing the metallic substrate 1.

2. Description of the Related Art Conventionally, in order to form a three-dimensional structure by providing a step on the upper surface of a display body formed by electroforming, a concave portion corresponding to the convex portion of the display body is engraved on the surface of a metal substrate,
Electroforming is performed on the surface of the metal substrate including the concave portion to mold the display body having the uneven portion, and the metal contact surface is used as the surface of the display body.
The other side was used as a mounting surface and was mounted on a mounting base such as a watch base.
