Abstract

An inverter (10) includes a power substrate (20) mounting power element groups (G1, G2, G3, G4, G5, G6) arranged apart from each other, each power element group constituted by power elements (24) arranged, a control substrate (60) disposed apart from the power substrate (20) in a plate thickness direction of the power substrate (20) and mounting an electronic component (63) for controlling the power elements (24), a capacitor substrate (50) disposed between the power substrate (20) and the control substrate (60) and mounting capacitors (54), a release member fixed to the power substrate (20), and a spacer (40) electrically connecting the power substrate (20) and the capacitor substrate (50). The spacer (40) includes a body portion (41) disposed between two adjacent power element groups (G1, G2, G3, G4, G5, G6) of the power element groups (G1, G2, G3, G4, G5, G6) and a heat transfer portion (42) disposed outside the power element groups (G1, G2, G3, G4, G5, G6) in a direction in which the power elements (24) are arranged and provided at a position not overlapping with the capacitors (54) as viewed in a plate thickness direction of the capacitor substrate (50).
