Claim of US Patent No. 10,716,222

1. A manufacturing method of a laminate body, comprising:a first step of forming onto a supporting body a curable resin composition layer formed from a thermosetting resin composition to obtain a curable resin composition layer with a supporting body;
a second step of laminating the curable resin composition layer onto a substrate by heat crimping, the curable resin composition layer contacting the substrate, to thereby obtain a pre-cured composite;
a third step of performing a first heating of the aforementioned pre-cured composite thereby thermally curing the curable resin composition layer to form a cured resin layer to obtain a cured composite;
a fourth step of performing hole punching from the supporting body side of the cured composite to form a via hole in the cured resin layer;
a fifth step of peeling the supporting body from the cured composite;
a sixth step of removing resin residue in the via hole of the aforementioned cured composite;
a seventh step of performing a second heating of the aforementioned cured composite; and
an eighth step of forming a conductor layer on an inner wall surface of the via hole of the cured composite and on the cured resin layer.
