There is provided a semiconductor device with which stress can be prevented from locally concentrating on an external connecting terminal on a post and thus damages of the external connecting terminal can be prevented. The semiconductor device includes a semiconductor chip, a sealing resin layer stacked on a surface of the semiconductor chip, and the post which penetrates the sealing resin layer in a stacking direction of the semiconductor chip and the sealing resin layer, protrudes from the sealing resin layer, and has a periphery of the protruding portion opposedly in contact with a surface of the sealing resin layer in the stacking direction. |
