Abstract

A wiring pattern (26) or (27) and conductor wires (W1, W2) or (W3, W4) not relaying a wiring pattern (22) or (23) fed with an emitter current connect emitter electrodes of a plurality of IGBTs (3) connected in parallel with each other. Thus, oscillation appearing on the potential of a control electrode of the plurality of IGBTs (3) is suppressed.
