PROBLEM TO BE SOLVED: To miniaturize an electronic control device having two circuit boards.SOLUTION: In an electronic control device 1, a first circuit board 10 and a second circuit board 11 are housed in a housing case 2 so as to vertically and partially overlap each other. A tall electronic component 32 and a short electronic component 33 are mounted on the first circuit board 10 located on the lower side. The short electronic component 33 is arranged in a region where the two circuit boards 10 and 11 overlap each other, and the tall electronic component 32 is arranged in a region where the two circuit boards 10 and 11 do not overlap each other. Since a space between the two circuit boards 10 and 11 can be narrowed, the electronic control device 1 can be miniaturized. |
