PROBLEM TO BE SOLVED: To prevent distortion or damage on a substrate in a housing due to external force applied to the outside of the housing.SOLUTION: Protruding bushes 21H-1 through 21H-4 are formed on a top surface 21A of an upper case 21, so as not to come into contact with an outer wall 21D. Furthermore, an inner wall 21B is formed on the top surface 21A, and connects the bushes 21H-1 through 21H-4 without coming into contact with the outer wall 21D. Four corners of a substrate are attached to the bushes 21H-1 through 21H-4. The invention is applicable to, for example, an ECU of a vehicle. |
