This power conversion device (100) is provided with: magnetic cores (21, 22); a plurality of windings (11, 12); a plurality of metal side walls (43, 44); first insulation members (61, 62, 63); and a second insulation member (64). The plurality of windings (11, 12) are wound around the outsides of the magnetic cores (21, 22), and are bent so as to be provided with sections extending in the direction in which the magnetic cores (21, 22) extend. The plurality of metal side walls (43, 44) are provided to the outside of the plurality of windings (11, 12), and extend along the direction in which the magnetic cores (21, 22) extend. The first insulation members (61, 62, 63) are provided between the plurality of windings (11, 12), and between the windings (11, 12) and the magnetic cores (21, 22). The second insulation member (64) is provided to the outside of the plurality of windings (11, 12) so as to be in contact with each of the plurality of side walls (43, 44) and each of the plurality of windings (11, 12). The thermal conductivity of the second insulation member (64) is higher than the thermal conductivity of each of the first insulation members (61, 62, 63). |
