Claim 0:
1. A semiconductor device comprising:
a first wiring substrate having a first surface and a second surface, the second surface opposite to the first surface, the first wiring substrate including a plurality of first electrode pads on the first surface;
a second wiring substrate having a third surface and a fourth surface, the third surface facing the first surface, the fourth surface opposite to the third surface, the second wiring substrate including a plurality of second electrode pads on the third surface;
a plurality of first semiconductor chips between the first surface and the third surface;
a first columnar electrode extending in an oblique direction relative to the first surface and the third surface, the first columnar electrode configured to connect the plurality of first electrode pads and the plurality of second electrode pads; and
a first resin layer configured to cover the plurality of first semiconductor chips and the first columnar electrode between the first surface and the third surface.
