Abstract:
An electronic control unit comprising:a substrate having a mount face and an opposite mount face; an electronic component located on a surface of the mount face, wherein the electronic component generates heat; a plurality of enclosure members defining an enclosure that houses the substrate, wherein at least one of the plurality of enclosure members is located on a side of the opposite mount face and includes a protrusion that faces toward a position where the electronic component is located; and a flexible, thermally conductive material located between the protrusion and the opposite mount face, wherein the flexible, thermally conductive material is in contact with a surface of the protrusion and a surface of the opposite mount face, wherein the enclosure member having the protrusion and the substrate are in direct contact with each other or are in contact with each other using a spacer that has a predetermined thickness so as to be fixed such that the height of the protrusion differs from the height of a contact area between the enclosure member having the protrusion and the substrate to provide a predetermined clearance between the protrusion and the substrate.
