In a GTO device in which a snubber circuit consisting of a capacitor, a diode, and a resistor for suppressing υ/at is individually grounded to the ends of the pair of cooling fins using lead wires, a cooling fin portion to which the lead wires are connected. Then, an auxiliary conductor having the same DC potential as one cooling fin is placed close to the other cooling fin in the space region formed by the cooling fin portion where the GTO element is held and the pair of cooling fins.
