Title: SEMICONDUCTOR DEVICE
Abstract:
The present invention addresses the problem of deterioration of insulation reliability. A length L2 from a center P of a conductor layer 334 to the periphery of an insulating member 333 is formed longer than a length L1 from the center P of the conductor layer 334 to the periphery of a protruding portion 307a of a base member 307. In other words, a base end surface 308 of the periphery of the protruding portion 307a is positioned further toward the inner side than an insulating member end surface 336 of the periphery of the insulating member 333. Furthermore, the insulating member end surface 336 of the insulating member 333, and a conductor layer end surface 344 of the conductor layer form an end surface at a same position. In such a manner, the base end surface 308 of the periphery of the protruding portion 307a is positioned further toward the inner side than the insulating member end surface 336 of the periphery of the insulating member 333, thereby ensuring insulation distance.
