干大きくしておく。A method for manufacturing the molding 2 is as follows. First, a resin member 3 made of a thermoplastic resin (soft PVC in the embodiment) is coated with a decorative member 4 such as a glitter or color tape on a part of an outer surface of the resin member 3 by extrusion molding or the like. A scale molding body 5 is formed. Then, as shown in FIG. 1 and FIG. 2, the molding body 5 is cut into a predetermined size, and the outer surface side of the terminal portion 7 including the decorative member 4 is cut off to form a cut portion 8. At this time, the volume of the terminal portion 7 after the cut portion 8 is formed is substantially the same as the volume of the terminal processed portion 6, and is slightly larger than the volume of the cavity 14.
