Abstract
An electric power conversion apparatus includes: a heat-generating element; a case having a cooling wall portion on which the heat-generating element is held and accommodating the heat-generating element; a flow passage cover having an opening formed therein and covering a surface of the cooling wall portion on the opposite side to the heat-generating element; a standing portion standing from the cooling wall portion and inserted in the opening; a flow-passage side wall portion formed in one of the cooling wall portion and the flow passage cover to protrude toward the other; a coolant flow passage surrounded by the cooling wall portion, the flow passage cover and the flow-passage side wall portion; and a sealant that seals both a gap between the cooling wall portion and the flow passage cover at a periphery of the coolant flow passage and a gap between the standing portion and the flow passage cover.
