A power conversion apparatus has: a heat-generating component; and a first capacitor module and a second capacitor module that are arranged to face each other with the heat-generating component therebetween. The first capacitor module has a first capacitor element, a first case that accommodates the first capacitor element, and a first bus bar with one end connected to the first capacitor element. The second capacitor module has a second capacitor element, a second case that accommodates the second capacitor element, and a second bus bar with one end connected to the second capacitor element. The second bus bar has an intervening part that intervenes between the second capacitor element and the heat-generating component, in a state of being separated from the two.

Power conversion apparatus

A power conversion device that can prevent decrease in sealing properties between a case and a fixed member. The power conversion device has a case, a fixed member, and a seal member. The case has a metallic case body. The fixed member is fixed to the case from the outside of the case. The seal member adheres closely to both the case and the fixed member to ensure water-tightness between the case and the fixed member. The case is partly formed with a corrosion-resistant portion that is less likely to suffer corrosion than the case body. The fixed member is attached to the corrosion-resistant portion via the seal member.
