Abstract
An electronic control unit (10) mounted in a vehicle engine compartment, having a plastic case body (14), metal collars (32) each molded into the plastic case body, a metal base (12) having bolt through-holes (28) prepared in the same number of the metal collars such that a bolt passes through each metal collar and one of the holes corresponding thereto, and a heat-generating component (18) mounted on the base. The characteristic features are that an outer surface of each metal collars (32) that comes in contact with the plastic case body (14) is formed with projections and depressions, each metal collar (32) is shaped to be protruded from the upper and lower ends of the plastic case body in the same direction as the bolt-through hole (28), and the plastic case body (14) and the metal base (12) are joined together with adhesive (40) in such a way that the metal collars and the metal base are fastened together with the bolts to be mounted in the engine compartment, thereby ensuring good mounting strength with superior watertightness.
