A semiconductor device includes: a pad; a control circuit; a plurality of high-potential-side circuit regions having distances to the pad different from each other, each including a gate drive circuit, a SET-side level shifter, a RESET-side level shifter, and a circular wire; a SET-side wire electrically connects the pad with the SET-side level shifters; and a RESET-side wire electrically connects the pad with the RESET-side level shifters, wherein the circular wire located closer to the pad is electrically connected to the SET-side wire and the RESET-side wire via the circular wire 8u located further from the pad.
