In this example, when the cushion body 1 for a seat is manufactured, an adhesive coating film 6 in which a substance having a high high-frequency dielectric constant is added to the hot melt adhesive 5 is applied to the mold pad 3, and then the mold pad 3 is subjected to a high-frequency wave. The adhesive coating film 6 is sandwiched and overlapped on the sheet cover 2 set on the pressing jig 12 in the generator 10, and the stack 7 of the sheet cover 2, the mold pad 3 and the adhesive coating film 6 is pressed. Then, the high frequency generator 10 oscillates a high frequency to dielectrically heat the stack 7 until the hot melt adhesive 5 rises to the melting temperature, and the sheet cover 2 and the mold pad 3 are hot melt adhesive. 5 is configured to be joined by the adhesive layer 4 that is solidified after melting.
