(57) [Summary] [Object] It is an object of the present invention to provide a novel mold and molding method that overcome the problems that occur in manufacturing a finder having a compound lens. In order to achieve the above object, a forming die according to the present invention is a forming die for forming a finder device, wherein an upper forming die member (5) having a first forming surface. And a lower mold member (7) having a second molding surface, the molding surfaces being spaced apart to form a molding chamber therebetween when the molding die is in a molding position. , At least two pairs of lens molding parts (20, 22, 24, 26) Each having a highly-finished surface, each face of each pair of lens-forming parts being arranged face-to-face to form a region for forming a lens in the forming chamber, The surface of the lens molding portion is configured to be substantially perpendicular to the molding surface. |
