Abstract

Low-voltage side wirings LWA and LWB extend in X-direction, respectively, while meandering along a main surface of a semiconductor substrate SUB. A high-voltage side wiring HAW is opposed to the meandering low-voltage side wiring LWA, and a high-voltage side wiring HWB is opposed to the meandering low-voltage side wirings LWB. The high-voltage side wirings HWA and HWB include: X-direction extending parts XA and XB extending in X-direction; and a plurality of Y-direction extending parts YA and YB extending, respectively, in Y-direction. Toward a section of the low-voltage side wiring LWA being away from the X-direction extending part XA, the Y-direction extending part YA has entered. Also, toward a section of the low-voltage side wiring LWB being away from the X-direction extending part XB, the Y-direction extending part YB has entered.
