Abstract: An electronic control unit includes: a substrate (10); a heat generating component (20) provided on one surface (11) of the substrate and generates heat during operation; a heat conducting component (40) formed of a material having a heat conductivity equal to or higher than a predetermined value and provided on the one surface of the substrate such that at least a part of the heat conducting component is located in a range (R1) of a predetermined distance (L) from the heat generating component; a controller (60) provided on the substrate and controlling the operation of the heat generating component to control the object to be controlled; and a radiator (70) provided adjacent to the one surface of the substrate to radiate heat from the heat generating component and the heat conducting component. A distance (d1, d3) between the heat generating component and the radiator is equal to or shorter than a distance (d2, d4) between the heat conducting component and the radiator.

Abstract: In an electronic control unit, high-heat-generating devices are mounted on a first surface or a second surface of a board, a heat-dissipating member is located facing the first surface of the board, and a heat-conducting member is located between the board and the heat-dissipating member. The heat-conducting member is in contact with the high-heat-generating devices to transfer heat of the high-heat-generating devices to the heat-dissipating member. A ratio of the number of the high-heat-generating devices mounted on the board to the number of the high-heat-generating devices arranged inside a first limited region of the first surface or a second limited region of the second surface is greater than a predetermined ratio. The second limited region is located at a position corresponding to the first limited region.
