To provide a decorative body sticking technology that can prevent the dislocation of a decorative body, reduce a material loss and simplify the whole apparatus.

A heater lifting cylinder 35 in Fig.(a) is operated to lower a heater 33 as shown by an arrow mark (8). A fluid ejection valve 52 is closed to stop a decompression pump 55. A fluid introducing valve 54 is opened to introduce a fluid into a container 13 as shown by an arrow mark (9). Since the inside of a storage member 24 is thereby reduced in pressure, the storage member 24 is compressed receiving pressure as shown by arrow marks (10), and the decorative body 27 is pressure-fitted and stuck to a decorated body 25. As a result, since the size of the decorative body can be smaller than that of the decorated body, the decorative body is formed into a required minimum size to reduce the material loss.
