Electronic control unit having positioning member for positioning base substrate and electronic device

An electronic control unit comprising:

• a base substrate including a first connector;
• an electronic device mounted on the base substrate to be substantially orthogonal to the base substrate, the electronic device including a wiring board and a second connector disposed on the wiring board to be electrically connected to the first connector;
• and
• a positioning member disposed between the base substrate and the electronic device and positioning the first connector and the second connector relative to each other, wherein
• the positioning member includes:
• a first protrusion inserted into a first positioning hole of the base substrate to position the positioning member with respect to the base substrate, the first positioning hole being disposed along a thickness direction of the base substrate;
• and
• a second protrusion inserted into a second positioning hole of the wiring board to position the positioning member with respect to the wiring board, the second positioning hole being disposed along a planar direction of the wiring board.
