[Problem] To improve cooling efficiency. [Solution] A power conversion device 1 comprising: a first substrate 30; second substrates 32 and 34 that are erected on the first substrate 30; power modules PM1 to PM8 that are arranged on the second substrates 32 and 34, that constitute a power conversion circuit 10, and that generate heat when energized; and capacitors C1 to C4 that are arranged closer to the first substrate 30 than the power modules PM1 to PM8, that form a part of a cooling flow path 75 for cooling the power modules PM1 to PM8, and that constitute the power conversion circuit 10. |
