Abstract: A capacitor module includes a smoothing capacitor, a P-side Y capacitor and a N-side Y capacitor as noise absorbing capacitors, a capacitor case, a P-side bus bar, a N-side bus bar, and a ground bus bar. A virtual plane along a P-side electrode surface, which is an electrode surface on a high potential side of the smoothing capacitor, is referred to as a P-side virtual plane. A virtual plane along a N-side electrode surface, which is an electrode surface on a low potential side of the smoothing capacitor, is referred to as a N-side virtual plane. A region between the P-side virtual plane and the N-side virtual plane is defined as a PN region. The entire noise absorbing capacitor and the entire ground bus bar are arranged in the PN region.

Abstract: A heat exchanger includes a plurality of fins that are spaced from each other and are arranged to divide a heat medium flow passage into a plurality of narrow passages. Each fin incudes a plurality of thick wall portions and a plurality of thin wall portions which are alternately arranged in a passage longitudinal direction. Each adjacent two of the plurality of fins, which are adjacent to each other, are defined as one fine and another fin, and each of the plurality of thick wall portions of the one fin is opposed to an adjacent one of the plurality of thin wall portions of the another fin in a fin arrangement direction, and each of the plurality of thin wall portions of the one fin is opposed to an adjacent one of the plurality of thick wall portions of the another fin in the fin arrangement direction.
