1. An electronic control device that controls an actuator, the electronic control device comprising:
a circuit board;
an electronic component mounted on the circuit board;
an insulating case that holds the circuit board;
a first fixing member that fixes the circuit board to the insulating case;
a first conductive cover that covers the insulating case;
a second conductive cover that holds the insulating case and covers an opening portion of the actuator;
a conductive portion that makes the first conductive cover and the second conductive cover conductive;
a second fixing member that fixes the first conductive cover to the insulating case in a non-contact state with the second conductive cover; and
a third fixing member that fixes the insulating case to the second conductive cover in a non-contact state with the first conductive cover.
