PROBLEM TO BE SOLVED: To provide an electronic control unit capable of suppressing the deterioration of radiative property by securing a radiation path through a radiation member even if external force such as shock or vibration is applied. SOLUTION: A circuit substrate 11 on which electronic parts including a heater element 12 is accommodated in a cubicle 1, and the heater element 12 and the cubicle 1 are thermally connected by interposing the radiation member 30 between the heater element 12 and the internal surface of the cubicle 1. As the radiation member 30, a polymer material having fluidity is used, and a film 40 that the radiation member 30 and the cubicle 1 are chemically or electrically bonded, which prevents the radiation member 30 from moving, is disposed between the radiation member 30 and the internal surface of the cubicle.
