Classification: CPC H | IPC H

Claim 0:
1. An electronic control device, comprising:
a substrate;
an electronic component mounted on the substrate;
an insulating case that holds the substrate;
a conductive cover that covers the insulating case;
a conductive base that holds the insulating case; and
a conductive fixture that fixes the insulating case to the conductive base,
wherein a distance L1 between the conductive cover and the conductive fixture is equal to or less than a distance L2 between the conductive cover and a conductive terminal of the electronic component,
wherein
a plurality of the conductive fixtures are provided,
a distance L1 between the conductive fixture closest to the electronic component and the conductive cover is equal to or less than a distance L2 between the conductive cover and a conductive terminal of the electronic component, and
a thermal conductive material disposed between the conductive cover and the electronic component and having a withstand voltage higher than a withstand voltage of air.
