PURPOSE:To contrive an improvement in fitting character even if molding accuracy is obtained at low cost and is rough, by molding plastics by making use of a molded body made of the plastics molded through a pair of a top and bottom forces as a mold. CONSTITUTION:A cavity which is in an identical shape with a cap 1 is formed by fitting a top force 5 into a bottom force 4 and the top force 5 is pulled out of the mold by melting and pouring plastics, whose melting temperature is comparatively high, into the cavity. A molded body made of plastics consists of an article obtained by leaving a molded cap 1 made of plastics within the bottom force 4 as it was and a flat mold, and among those the bottom of a button of the flat metal mold is made larger than an opening part of a stepped part 4a. A cavity which is in an identical shape with the button is formed by abutting the flat metal mold against the bottom force 4 within which the cap 1 is left behind as it was, and the titled product is molded by pouring plastics, whose melting temperature is low, into the cavity.
