<p>The present invention provides a high-reliability, inexpensive power converter that minimizes connection failures and other faults, obviates dedicated connection fittings, and allows wire material to be shortened. This power converter (1) has a plurality of mounting substrates (21, 22, 23) arranged facing each other across a gap. A control circuit substrate (23) is supported without providing a heat transfer support member (32, 33) on the lateral periphery of the control circuit substrate (23), the heat transfer support member (32, 33) constituting a shielding part. A power-source circuit substrate (22) has a laterally disposed shielding part derived from the heat transfer support member (32, 33). In the control circuit substrate (23), an external connector (50) is near a first side (23f) and an inter-substrate connector (60) is arranged near a second side (23s) opposite the first side (23f). In the power-source circuit substrate (22), an inter-substrate connector (60) is arranged near a third side (22t) that is the same side as the second side (23s) of the control circuit substrate (23) and is devoid of a shielding part.</p> |
