摘要: An object of the invention is to provide a printed circuit board that has an excellent heat dissipation performance and excellent reliability, and its manufacturing method. The printed circuit board includes: prepregs (2a) and (2b) being cured after each covering the surfaces of a metal plate (1) provided with first throughholes (1a) therein and the inner walls of the first throughholes (1a); prepregs (4a) and (4b) being cured after glass clothes (3a) and (3b) are sandwiched between the prepregs (2a) and (2b), and the prepregs (4a) and (4b), respectively; and second throughholes (8) that connect wiring layers (7a) and (7c), and (7b) and (7d) provided on both surfaces of prepregs (6a) and (6b), respectively. The prepregs (2a) and (2b) and the prepregs (4a) and (4b) are characterized in that they contain inorganic filler. Furthermore, the prepregs (2a) and (2b) and the prepregs (4a) and (4b) may contain elastomer.
