Abstract: To provide a manufacturing method of a laminate body, including: a 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 step of laminating the curable resin composition onto a substrate on a curable resin composition layer forming surface side to obtain a pre-cured composite with a supporting body formed from a substrate and a curable resin composition layer with a supporting body; a step of performing a first heating of the pre-cured composite and thermally curing the curable resin composition layer to obtain a cured composite with a supporting body formed from a substrate and a cured resin layer with a supporting body; a step of performing hole punching from the supporting body side of the cured composite with a supporting body to form a via hole in the cured resin layer; step of removing resin residue in the via hole of the cured composite with a supporting body; a step of peeling the supporting body from the cured composite with a supporting body to obtain a cured composite formed from a substrate and a cured resin layer, and a step of forming a dry plated conductor layer by dry plating on an inner wall surface of the via hole of the cured composite and on the cured resin layer.
