Abstract:
1. A method of producing a component built-in module including an insulating layer, wirings integrated with both surfaces of the insulating layer, a via connecting the wirings, and one or more components selected from an electronic component and a semiconductor, which is embedded inside of the insulating layer, wherein at least one of the wirings is formed on a surface of a wiring board, comprising the steps of: mounting the one or more components selected from an electronic component and a semiconductor on the wiring board; forming the via along a thickness direction of the insulating layer, where the insulating layer is made of a thermosetting resin in a semi-cured state; embedding the components in the insulating layer so that the wiring board is arranged outside; and curing the insulating layer.
