    Abstract: The present invention provides a method for manufacturing a decorative piece made of a thermoplastic synthetic resin and capable of providing a suede-like appearance. The method for manufacturing the decorative piece 10 comprises preparing a film-like or sheet-like upper layer material 30 made of thermoplastic synthetic resin, placing the upper layer material on a table 46 that serves as a lower electrode, putting an engraved die 41 that serves as an upper electrode on the upper layer material, and subjecting the upper layer material to high-frequency dielectric heating by oscillating high-frequency between the table and the engraved die, wherein the upper layer material is printed with a decorative ink containing urethane beads mixed in medium on a specified surface area 31 thereof, and wherein the engraved die has a texture engraved surface 42 formed by a laser engraving process on an area opposing the specified surface area of the upper layer material, whereby a suede-like unevenness is formed in the specified area of the upper layer material by the high-frequency dielectric heating.

    Abstract: A three-dimensional decorative piece that is made of a thermoplastic synthetic resin and can retain bulkiness and shape by a core and a method of producing the same. The three-dimensional decorative piece includes an upper layer molded body made of an upper layer material with a metal vapor-deposited layer and having a three-dimensional shape with a convex portion formed on its front surface side through a high-frequency dielectric heating, a core formed by curing a flowable synthetic resin filled in the convex portion of the upper layer molded body, and a substrate bonded a back surface side of the core by fusion.
