Patent ID: 7165321

Claim:
A method for manufacturing a printed wiring board, the method compnsing: preparing a plurality of conductive layer films, each of which includes a resin film made of thermoplastic resin, a conductive layer formed on one side of the resin film, a bottomed via-hole which is bottomed by the conductive layer, and a conductive paste packed in the bottomed via-hole; preparing a sheet member in which a recess or an opening is formed, the sheet member beinig made of the same thermoplastic resin to the resin film, wherein no conductive layer and no bottomed via-hole is formed in the sheet member: stacking the plurality of conductive layer films; placing the sheet member on an outer surface of or in a stacked body of the conductive layer films, wherein the stacked body is formed at the step of stacking; inserting an electric device in the recess or the opening formed in the sheet member; and bonding the conductive layer films and the sheet member by pressing and heating the conductive layer films and the sheet member after the step of inserting.
