Abstract

A method for manufacturing a wiring board comprising an insulating member, comprising: a penetrating hole formation process of forming a penetrating hole in the insulating member; a placement process of inserting a conductive connecting particle into the penetrating hole; a connecting particle pressing process of disposing the conductive layers on both surfaces of the insulating member, pressing the conductive layers toward the connecting particle in the penetrating hole, and deforming the connecting particle in the pressing direction to obtain the connecting member; and a patterning process of patterning the conductive layers, wherein, in the connecting particle pressing process, the pressing is performed such that the cross-sectional area in the direction along the insulating member surface of at least a portion of the connecting member is greater than the contact area of the connecting member with the conductive layers.
