Abstract:
1. A manufacturing method of a printed wiring board, comprising: providing a plurality of plate-like laminates each comprising a resin layer, a first metal foil laminated to one side of the resin layer, and a second metal foil laminated to an opposite side of the resin layer; bringing the plate-like laminates into contact with each other such that adjacent ones of the plate-like laminates form contact portions with end portions of the plate-like laminates contacting each other such that a surface of the first metal foil of one plate-like laminate directly contacts a surface of the second metal foil of an adjacent plate-like laminate; linearly joining the contact portions of the plate-like laminates formed by repeating the bringing of the plate-like laminates so as to obtain a long laminate comprising the plurality of plate-like laminates joined in repetition and to successively extend a length of the long laminate; winding up the long laminate onto a roller as the length of the long laminate is continuously added by repeating the bringing of the plate-like laminates and the joining of the contact portions of the plate-like laminates; and processing the long laminate comprising the plate-like laminates.
