PROBLEM TO BE SOLVED: To provide an electronic control device which inhibits an opening of a passage formed by a first case side joint part and a second case side joint part from being exposed to water and thereby improves the waterproofness.SOLUTION: An electronic control device 10 includes: a circuit board 20 on which electronic components are mounted; a housing 40 which houses the circuit board with a lower case 50 and an upper case 60; and a seal member 70 disposed between a lower case side joint part 52 and an upper case side joint part 63. The lower case side joint part 52 extends to the outer side further than an outer end surface 66 of the upper case side joint part 63. A cover part 55, which covers an opening 42a of a passage 42 formed by arranging the lower case side joint part 52 and the upper case side joint part 63 so that the lower case side joint part 52 and the upper case side joint part 63 face each other through a gap, is formed at an area to which the lower case side joint part 52 extends.SELECTED DRAWING: Figure 8 |
