Claim 0:
1. A method for manufacturing a printed wiring board, comprising:
forming a seed layer on a surface of a resin insulating layer;
applying a dry film onto the seed layer using a laminating roll device;
cutting the dry film applied onto the seed layer to a predetermined size;
applying a pressure and heat to the dry film applied onto the seed layer;
forming a plating resist on the seed layer from the dry film using a photographic technology;
forming an electrolytic plating film on part of the seed layer exposed from the plating resist;
removing the plating resist from the seed layer; and
removing the part of the seed layer exposed from the electrolytic plating film,
wherein the applying of the pressure and heat to the dry film applied onto the seed layer comprises applying the pressure and heat to the dry film applied onto the seed layer such that the pressure and heat are applied to an entire surface of the dry film cut to the predetermined size simultaneously and that the applying of the pressure and heat to the dry film is conducted after the applying of the dry film onto the seed layer and includes applying the pressure to the dry film via a pressure application gas.
