Abstract

An electronic control device includes a board including a heat sink on which a heat generation element is mounted, and a housing that is in contact with the board and dissipates heat of the heat generation element to the outside. A potential of the housing is a ground, and a potential of the heat sink is a non-ground. The board includes a first layer including a first non-ground wiring that is in direct contact with the heat sink, and a second layer including a second ground wiring that is in electrical and thermal contact with the housing. The first non-ground wiring and the second ground wiring overlap each other in plan view from a thickness direction of the board.
