Provided is a power module capable of welding a snubber capacitor without causing melting damage to a resin housing by welding heat. When leads of a snubber capacitor are respectively welded to upper surfaces of the specific portions of a P-pole bus bar and an N-pole bus bar, the welding heat generated at the specific portions of the P-pole bus bar and the N-pole bus bar is respectively radiated from openings, through which the lower surfaces of the specific portions of the P-pole bus bar and the N-pole bus bar are exposed. As a result, the snubber capacitor can be later appended by welding without causing melting damage to the resin housing due to the welding heat. During welding, a separate cooling head is inserted into the openings to forcibly cool the lower surfaces of the specific portions of the P-pole bus bar and the N-pole bus bar respectively, so that the melting damage to a resin housing can be more reliably avoided.
