Abstract
A power conversion device includes a casing, a first printed board, a second printed board, and a control circuit board. The casing has at least two inner surfaces. The first printed board is fixed to the inner surface of the casing. The second printed board is fixed to the inner surface of the casing, and disposed so as to intersect with the first printed board. The control circuit board is disposed along the second printed board. The control circuit board includes a circuit wiring and a shield pattern opposite to the circuit wiring in a layer different from the circuit wiring. When viewed from an opposite direction in which the shield pattern is opposite to the circuit wiring, the shield pattern at least partially overlaps the circuit wiring.
