Abstract:
1. A method for manufacturing a substrate with a metal film, comprising: preparing an insulative substrate having a first surface and a second surface on an opposite side of the first surface; forming in the insulative substrate a penetrating hole having an inner wall tapering from the first surface of the insulative substrate toward the second surface; forming a layer of a composition comprising a polymerization initiator and a polymerizable compound on the inner wall of the penetrating hole; irradiating the layer of the composition with energy such that the polymerizable compound in the composition undergoes polymerization and a polymer is produced through the polymerization of the polymerizable compound and formed on the inner wall of the penetrating hole; applying a plating catalyst on the polymer; and forming a plated-metal film on the inner wall of the penetrating hole.
