Claim:
1. A semiconductor device, comprising: an insulated circuit board having at least one semiconductor element bonded to the first metal layer; a printed wiring board facing the first metal layer and extended over the plurality of island regions; first conductive pins each having one end fixed to the printed wiring board and another end soldered to a surface electrode of the at least one semiconductor element; second conductive pins each having one end fixed to the printed wiring board and another end soldered to the first metal layer; and third conductive pins each having one end fixed to the printed wiring board and another end soldered to the first metal layer, the third conductive pins being electrically isolated from an electric circuit of the printed wiring board, wherein each of a first island region and a second island region of the plurality of island regions has at least one of the third conductive pins arranged thereon, the first and the second island regions are distanced from each other by a gap between the first and the second island regions, and for each of the first and second of the island regions, each of the third conductive pins thereon are connected to the first metal layer at a position distanced from the gap at least as far as a distance, from the gap, of each of the first conductive pins and the second conductive pins thereon.
