PROBLEM TO BE SOLVED: To solve the problem that when a sheet made of a fiber-reinforced thermoplastic resin which has been heat-softened is compression-molded, if the cooling solidification is insufficient, the sheet thickness of an attaching sheet surface becomes uneven by the expansion of the sheet after being released from the die, and a desired sheet thickness accuracy cannot be obtained, and on the contrary, when the cooling solidification is sufficiently performed in order to obtain the desired sheet thickness accuracy, the molding cycle becomes longer, and causes the increase of costs. SOLUTION: A die clearance at a location being equivalent to a pilot hole for attaching a partner part in a vicinity of the center of the partner part attaching seat surface of the compression-molding die for the sheet is made larger than a die clearance at a location being equivalent to the partner part attaching seat surface to solve the problem.
