<p>In the present invention, with respect to a laminated structural body wherein at least an A-layer mainly formed of a thermoplastic resin (P1) having a melting point (Tm1), and a B-layer mainly formed of a thermoplastic resin (P2) having a glass-transition temperature (Tg2) are formed, a molding die having a protruding structure on the surface is pressed to the A-layer side of the laminated structural body, in a state wherein the molding die is heated to a temperature equal to or higher than a higher one of the temperature (Tm1) and the temperature (Tg2), thereby forming through holes, which are disposed at desired positions and density distribution in the A-layer, and which have desired shapes.</p> |
