1. An electronic control unit comprising:a substrate; a housing to which the substrate is fixed;
a plurality of heating elements that are mounted on a surface of the substrate on the housing-side; and
a radiating component that is provided between the plurality of heating elements and the housing, wherein:
a surface of the housing on the substrate-side includes:
a plurality of accommodating recesses in each of which a corresponding one of the plurality of heating elements is accommodated;
a partitioning wall part that separates the plurality of healing elements from each other;
a peripheral wall part that surrounds the plurality of accommodating recesses and the partitioning wall part; and
a plurality of buffer parts each of which is a step and formed between a corresponding one of the plurality of accommodating recesses and the peripheral wall part; and
wherein each of the plurality of buffer parts is formed to be higher than a bottom part of a corresponding one of the plurality of accommodating recesses, and to be lower than the peripheral wall part, with respect to a reference surface that is a surface of the housing opposite to the surface of the housing on the substrate-side, and
wherein a distance from a surface of each of the plurality of buffer parts to the surface of the substrate on the housing-side in a thickness direction of the substrate is smaller than a distance from the bottom part of the corresponding one of the plurality of accommodating recesses to the surface of the substrate on the housing-side in the thickness direction of the substrate.
