Abstract
To provide an electronic control device capable of suppressing leakage of radio-frequency radiation noise, radiated from a noise source, to the outside. The electronic control device includes a radio-frequency circuitat least a part of which is driven at a radio frequency, a printed circuit boardon which a low-frequency circuitthat is driven at a low frequency is mounted, a housingmade of metal that includes therein the printed circuit boardtogether with the radio-frequency circuitand the low-frequency circuit, a plurality of radio-frequency connectorstofor transmitting and receiving signals related to the radio-frequency circuitmounted on the printed circuit boardto and from the outside of the housing, a low-frequency connectorfor transmitting and receiving signals related to the low-frequency circuitmounted on the printed circuit boardto and from the outside of the housing, and a partition wallfor suppressing propagation of radiation noise, radiated by driving the radio-frequency circuit, to the low-frequency connector
