Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device, comprising:
an insulating member having an electrical insulating property and having an insulating main face and an insulating rear face that are directed to sides opposite to each other in a thickness direction;
a main face wire having a wire main face and a wire rear face that are directed to the sides opposite to each other in the thickness direction, the main face wire being stacked on the insulating main face such that the wire rear face is opposed to the insulating main face;
a semiconductor element that is conductive to the main face wire and arranged on a side opposite to the insulating member with respect to the main face wire in the thickness direction;
a sealing resin having a resin side face directed in a direction crossing the thickness direction, the sealing resin sealing the main face wire and the semiconductor element;
a through-wire that is conductive to the main face wire and extending in the thickness direction from the wire main face, the through-wire having an exposed rear face that is exposed from the insulating rear face; and
a column conductor that is conductive to the main face wire and extending to a side opposite to the through-wire in the thickness direction from the wire main face, the column conductor having an exposed side face that is exposed from the resin side face, wherein
the column conductor is supported from opposite sides of the column conductor in the thickness direction by the insulating member and the sealing resin,
the main face wire has a side face side protrusion extending toward a side of the exposed side face farther than the through-wire,
the column conductor is stacked at a portion of the wire main face corresponding to the side face side protrusion, and
the column conductor and the side face side protrusion are sandwiched by the sealing resin and the insulating member in the thickness direction such that the sealing resin is in contact with a surface of the column conductor.
