Abstract
An electronic control device comprises a circuit board on which electronic components are mounted, a connector block integrated with a connector that is electrically connected to the circuit board, a base to which the circuit board is fixed, and a cover that can be fitted to circumferential grooves that are formed in the base and the connector block respectively so that a connecting portion of the connector protrudes to the outside while accommodating the circuit board that is fixed to the base. Furthermore, a ventilation hole is formed in a section of the connector block excluding a formation position of the connector so as to communicate an inner space with an outer space of the cover, and a sealing material that seals the ventilation hole is further provided.
