Abstract: A transfer layer is transferred well to a step portion. In a transfer mold body, a projection and indentation portion is formed to a front face of a bottom wall of a step portion. When covering a transfer film over a base member, air between the transfer film and the step portion is accordingly expelled from between indented portions of the projection and indentation portion and the transfer film at an edge portion of the bottom wall. The transfer film can accordingly be covered over the step portion whilst suppressing air from remaining between the transfer film and the step portion. A transfer layer of the transfer film can accordingly is transferred well to the front face of the step portion.

Abstract: In a transfer mold body, a display portion is formed from a crystalline resin and a main body portion is formed from an amorphous resin. Accordingly, a transfer layer is only transferred to the amorphous resin formed main body portion that has good transfer properties for the transfer layer, and the transfer layer is not transferred to the crystalline resin formed display portion that has poor transfer properties for the transfer layer. Accordingly, only the main body portion is decorated by the transfer layer, with the display portion to which the transfer layer is not transferred visibly displayed as the letter. Accordingly, since printing process is not necessary, suppressing an increase in cost of the transfer mold body. Moreover, the position of the letter is determined by two-color molding of the main body portion and the display portion, enabling positional displacement of the letter to be suppressed.
