PROBLEM TO BE SOLVED: To increase the adhesive strength of an adhesive on a control unit whose casing and cover are sealed therebetween by the adhesive, and to improve its heat radiation using the adhesive. SOLUTION: A ridged protrusion 410 continuously extending along an end edge of the cover 400 is formed on an application face 402 for the adhesive BO on the cover 400. This improves the fitness of the adhesive BO applied when the cover 400 is attached to the casing 300 and further improves its impermeability to water owing to the increased adhesive strength. As the adhesive BO is pushed into the peripheral edge side of a printed board 200, in addition, the heat of the printed board 200 is transmitted to the casing 300 and the cover 400 via the adhesive BO, thereby improving the heat radiation.
