Claim 5:
6. The device according to claim 1, further comprising:
a fifth insulating film extending downward from the upper surface of the first semiconductor layer;
a seventh electrode located in the fifth insulating film, the seventh electrode extending in the vertical direction;
an eighth electrode located higher than the upper surface of the first semiconductor layer, the eighth electrode overlapping a portion of the fifth insulating film, a portion of the first semiconductor layer, and a portion of the second semiconductor layer when projected onto the plane;
a second wiring member extending from the third electrode toward a termination region of the device, the second wiring member being electrically connected to the third electrode;
a third wiring member extending from the eighth electrode toward the termination region, the third wiring member being electrically connected to the eighth electrode;
a sixth insulating film located between the eighth electrode and the fourth electrode, between the eighth electrode and the first semiconductor layer, and between the eighth electrode and the second semiconductor layer; and
a fourth wiring member located above the second and third wiring members in the termination region, the fourth wiring member being electrically connected to the second and third wiring members.
