PROBLEM TO BE SOLVED: To provide an electronic unit attachment structure having a simple structure and allowed to be downsized.SOLUTION: An electronic unit attachment structure 1 is a structure for attaching an electronic unit 3 to an upper surface of a case 4 of an electric connection box 2. A case 5 of the electronic unit 3 includes a case body 50, a rectangular parallelepiped projection part 51 projected from one side surface 50c of the case body 50, a spring piece 53 extended from a side surface of the projection part 51, and a lock part 52 attached to the other side surface 50d. The case 4 includes a vertical wall 6 on which an insertion part 61 is formed and a lock receiving part 42. When the projection part 51 and the spring piece 53 are inserted into the insertion part 61 and the electronic unit 3 is rotated around the projection part 51, an upper surface of the projection part 51 is abutted on an inner surface of the insertion part 61, the spring piece 53 is elastically brought into contact with the inner surface of the insertion part 61, the lock part 52 is engaged with the lock receiving part 42, and the electronic unit 3 is attached to an upper surface of the case 4. |
