Abstract: A capacitor module is provided which includes a plurality of capacitors, a capacitor case, and a sealing resin with which the capacitor case is filled to seal the capacitors in the capacitor case. The capacitor case includes inward-facing portions of an outer wall thereof each of which bulges or protrudes between every adjacent two of the capacitors. As viewed in a height-wise direction perpendicular both to a direction in which the inward-facing portions protrude and to a direction in which two of the capacitors adjacent each other across one of the inward-facing portions are aligned, the intervening inward-facing portion traverses a line segment passing through centers of the two adjacent capacitors. This structure minimizes thermal interference between the capacitors.
