Patent ID: 8839520

Claim:
A manufacturing method of a device that has a semiconductor element, comprising: forming a first wiring on a first surface of a first member; forming a second wiring on a second surface of a second member so as to have a gap from a connection terminal and a third wiring on an inclined plane side surface of the second member, the second member disposed on the first surface of the first member, the second surface facing in a same direction as the first surface of the first member, the third wiring positionally aligned with the first wiring and the second wiring for connecting the first wiring and the second wiring; disposing the semiconductor element on the first surface of the first member or on the second surface of the second member; and providing plating that electrically connects the first wiring, the second wiring, the third wiring, and the connection terminal of the semiconductor element, wherein the connection terminal is disposed so as to face the second wiring, and the plating is provided in the gap between the connection terminal and the second wiring.
