PROBLEM TO BE SOLVED: To provide an electronic control device that is able to acquire air permeability and waterproofness for the interior of a housing by restricting protrusion of the housing toward the outer peripheral side.SOLUTION: A circuit board 4 on which an electronic component is mounted is accommodated in the internal space of a housing 1 formed by joining a plurality of housing members such as a case 2, a cover 3, etc. A ventilation passage 50 is formed in the housing member 3. The ventilation passage comprises: a thickness-part through-hole 5 having external-wall openings 36a, 36b located with a distance between them in the peripheral edges of the external walls of thick parts as of corner parts 30 or angular parts 35 and formed through a space between the external wall openings 36a, 36b; a communication hole 6 communicating with the internal wall 37 of the thick part and the through-hole 5 of the thick part; and an air permeable waterproof film 7 mounted in the inside opening 6a of the communication hole 6 on the inside of the housing 1.SELECTED DRAWING: Figure 1
