Abstract: An electronic control device includes a heating element, a substrate, and a housing. The heating element includes an electronic component. The heating element is mounted to the substrate. The substrate is fixed to the housing via a substrate fixing portion. The housing includes a plurality of projecting portions projecting to the substrate side from a reference surface. The plurality of projecting portions have mutually different heights from the reference surface. The reference surface is a surface opposing the substrate and a reference of a height of the housing. The projecting portion highest in the height from the reference surface among the plurality of projecting portions is in contact with a surface of the substrate via a heat dissipation member. The surface of the substrate is on an opposite side of a surface where the heating element is mounted.
