    摘要: A method wherein a bulky three-dimensional emblem can be made of a thermoplastic synthetic resin containing a vapor-deposited-metal laminated film. An apparatus for producing a three-dimensional emblem made of a thermoplastic synthetic resin includes a slide jig in which an electrode flat plate die and an electrode projecting die are slidable in a horizontal plane, an electrode recessed die capable of approaching and separating from the slide jig in a vertical direction and at a position where it can oppose the electrode flat plate die and the electrode projecting die, and a high-frequency oscillator that performs high-frequency dielectric heating by continuously generating a high-frequency voltage across the opposing dies, wherein recesses form in a surface of the electrode flat plate die opposing the electrode recessed die, and during high-frequency dielectric heating, a portion of the lower layer material enters the recess and is held on the electrode flat plate die.
