Patent ID: 8710639

Claim:
A wiring substrate in which a semiconductor element is built, the wiring substrate comprising: a semiconductor element; a peripheral insulating layer covering at least an outer circumferential side surface of the semiconductor element; and an upper surface-side wiring line provided on the upper surface side of the wiring substrate, wherein the semiconductor element includes, on the upper surface side thereof, an internal terminal electrically connected to the upper surface-side wiring line, the internal terminal includes: a first conductive part exposed out of an insulating surface layer of the semiconductor element; an adhesion layer on the first conductive part; and a second conductive part on the adhesion layer, and the adhesion layer covers an exposed surface of the first conductive part, and is formed on a portion of the insulating surface layer around the exposed surface of the first conductive part, and the adhesion layer extends around the outer side of an outer edge of the second conductive part so as to surround the second conductive part.
