Description

This invention relates to decorative members, methods for manufacturing decorative members, emblems, and movable bodies. For example, as shown in Patent Document 1, a decorative molded body having a molded portion, a decorative portion, and a hard coat layer is known. The decorative member is manufactured by first forming the molded portion by injection molding resin into one side of the decorative portion, and then forming a hard coat layer on the other side of the decorative portion. The hard coat layer is formed after the temperature of the decorative portion, which was heated by injection molding, has cooled. This is because if the hard coat layer is formed on the decorative portion before injection molding the molded portion, there is a risk that the decorative portion will expand during injection molding, causing the hard coat layer to crack.
