Abstract
An electronic control device including a circuit substrate having a signal wiring and a ground wiring; at least one connector having a signal conductor and a ground conductor respectively connected to the signal wiring and the ground wiring of the circuit substrate on one end side and extending on the other end side; a housing including an accommodating portion that accommodates the circuit substrate and the at least one connector, in which a radio wave path through which a leakage electromagnetic wave propagates from one end on the circuit substrate side toward the other end on the side opposite to the circuit substrate side of the at least one connector is formed in an internal space at the periphery of the at least one connector; and a leakage electromagnetic wave attenuating structure provided between the housing and the at least one connector; where the leakage electromagnetic wave attenuating structure includes a plurality of conductors that are arrayed along a direction in which the leakage electromagnetic wave propagates from the one end of the at least one connector, and attenuate the leakage electromagnetic wave propagating through the radio wave path.
