ELECTRONIC CONTROL UNIT

摘要

Heating elements are mounted on a substrate. A heat sink is provided to be capable of releasing heat of the heating elements. Each radiating component is provided between a corresponding one of the heating elements and the heat sink, and is provided in a corresponding one of radiating regions. Each radiating region includes a corresponding one of mounting portions of the heating elements. A gap part is formed in an area surrounded by the radiating components each of which is provided at a corresponding one of the radiating regions. Each heating element is located in a corresponding one of the radiating regions. There is not any one of the radiating components disposed at the gap part.
