摘要： An electronic device maintains a pressure adjustment function of a breathable filter. The electronic device includes a connector that includes a connector housing that closes an opening portion of a housing accommodating a circuit board and holds a connection terminal enabling electric connection of the circuit board to an external connector and a communication hole that penetrates the connector housing and allows an internal space and an external space of the housing to communicate with each other, and a filter attached to the connector housing to cover a first opening that opens in the communication hole on an internal space side of the housing. The connector housing has a shielding wall surrounding the periphery of the second opening of the communication hole that opens to the external space side of the housing and protrudes toward the external space side of the housing from the second opening of the communication hole.

摘要： An object of the present invention is to provide an electronic control unit that curbs overflow of a sealant at a three-way junction of the sealant in the vicinity of a connector. The electronic control unit includes a first seal part 51 that seals between a base member 40 and a cover member 30, a second seal part 52 that seals between the base member 40 and a connector housing 20, and a third seal part 53 that is connected to the first seal part 51 and the second seal part 52 and seals between the cover member 30 and the connector housing 20. In a part (three-way junction) where the first seal part 51, the second seal part 52, and the third seal part 53 intersect, a space part 41JA1 that is connected to the recessed part 41 and recessed further from a surface forming the recessed part 41 is formed.
