Zusammenfassung:	A semiconductor device includes a second deep layer between a first deep layer and first current distribution layer and a base region in an active region and in a part of an inactive region adjacent to the active region. The second deep layer has a second stripe portion including lines connecting to the base region and the first deep layer. The semiconductor device further includes a second current distribution layer between the first current distribution layer and the base region and arranged between the lines of the second stripe portion. The first deep layer has a first stripe portion including a plurality of lines, and each line has an end portion connecting to a frame-shaped portion and an inner portion on an inner side of the end portion. The width of the end portion is equal to or greater than the inner portion.
