Claim Text:
1. A substrate having a built-in electronic component, comprising: an insulating substrate having an opening portion; a conductor pattern formed on the insulating substrate; an electronic component accommodated in the opening portion of the insulating substrate and having a terminal; an insulating layer formed on the insulating substrate such that the insulating layer is covering the conductor pattern on the insulating substrate and the electronic component in the opening portion of the insulating substrate; and a plurality of via conductors penetrating through the insulating layer and comprising a first via conductor reaching to the conductor pattern on the insulating substrate and a second via conductor reaching to the terminal of the electronic component in the opening portion of the insulating substrate, wherein the conductive pattern has a recessed connecting portion connected to the first via conductor, the terminal of the electronic component has a recessed connecting portion connected to the second via conductor, and the recessed connecting portion of the conductor pattern has a depth which is greater than a depth of the recessed connecting portion of the terminal of the electronic component.
