Air circulation passages connect an accommodation space of an electronic control unit to the outside to circulate air to buffer internal pressure fluctuations. The accommodation space side of the air circulation passages is formed as a divided air circulation passage with a plurality of passages, a cooling object member is arranged to come in thermal contact with air flowing through the divided air circulation passage, and the total cross-sectional area of the divided air circulation passage is smaller than the cross-sectional area of the air circulation passages that are not divided. Because the accommodation space of the electronic control unit is connected to the outside, internal pressure fluctuations can be buffered, and increasing the flow velocity of the air flowing through the divided air circulation passage on the accommodation space side of the air circulation passages allows heat inside the accommodation space to be efficiently radiated to the outside.
