ABSTRACT:
A component built-in module includes an electric insulation layer, first wiring patterns in a plurality of layers that are laminated with the electric insulation layer being interposed therebetween, at least one first inner via electrically connecting the first wiring patterns in different layers with each other, and at least one electronic component that is embedded in the electric insulation layer and is mounted on any one of the first wiring patterns in the plurality of layers, wherein at least one of the first inner vias is present in a range that overlaps a range in which the electronic component is present in a lamination direction in which the first wiring patterns are laminated, and has a height in the lamination direction that is smaller than a height of the electronic component. Since the first inner via has a small height, the via diameter can be decreased. Therefore, it is possible to provide a component built-in module that has high reliability and is suitable for high-density component mounting.
