Abstract
An electronic control unit includes: a wiring substrate having a first surface on which a conductor wire is formed; a first electronic component that is implemented on the first surface of the wiring substrate, and has a large heat generation amount; a second electronic component that is implemented on the first surface of the wiring substrate, and has a heat generation amount smaller than the first electronic component; and a resin that covers the first electronic component, the second electronic component, and the first surface of the wiring substrate, and a second surface of the wiring substrate that is opposite to the first surface. A distance between an outer surface of the resin immediately below the first electronic component, and the second surface of the wiring substrate is longer than a distance between an outer surface of the resin immediately above the second electronic component, and the first surface of the wiring substrate.
