A method for manufacturing a printed wiring board including providing a support member having a metal surface, securing a metal foil to the metal surface such that the metal foil is joined or bonded to a peripheral portion of the metal surface, forming a resin insulation layer on the metal foil secured on the metal surface, forming an opening for a via conductor in the resin insulation layer, forming a conductive circuit on the resin insulation layer, forming in the opening a via conductor electrically connecting the conductive circuit and the metal foil such that a laminated sheet body is formed, and cutting a portion of the laminated sheet body inside the peripheral portion of the metal surface of the support member such that the metal foil releases the portion of the laminated sheet body from the support member.
