To provide an in-vehicle power converter that can be miniaturized while realizing a shield function by a GND pattern.SOLUTION: At least an in-vehicle power converter installed in a vehicle powered by a motor includes a conductive housing with an opening, and a multi-layer printed wiring board on which a circuit component is mounted, and the multi-layer printed wiring board is assembled to the opening of the conductive housing to form a closed space by the multi-layer printed wiring board and the conductive housing, and the circuit component is housed in the closed space, and at least one layer of the multi-layer printed wiring board is a GND plane, the GND plane is electrically connected to the conductive housing, and the multi-layer printed wiring board includes a first insulating layer and a second insulating layer having a higher insulating resistance than the first insulating layer has, between at least the circuit board and the GND plane.SELECTED DRAWING: Figure 2

    【課題】GNDパターンによるシールド機能を実現しつつ、小型化することが可能な車載電力変換装置を提供すること。【解決手段】少なくともモータを駆動源とする車両に搭載される車載電力変換装置であって、開口部を有する導電性筐体と、回路部品が実装される多層プリント配線板と、を備え、多層プリント配線板は、導電性筐体の開口部に組付けられて、多層プリント配線板と導電性筐体による閉空間が形成され、回路部品は、閉空間内に収納され、多層プリント配線板は、少なくとも1層がGNDプレーンであり、GNDプレーンは、導電性筐体に電気的に接続され、多層プリント配線板は、少なくとも回路部品とGNDプレーンの間に、第1絶縁層と、第1絶縁層よりも絶縁抵抗の大きい第2絶縁層を備える。【選択図】図2
