An electronic control unit comprising:

• first and second power modules on which switching elements are respectively mounted;
• an input and output board on which an input connector and an output connector to be connected to an electric motor are mounted, and which is connected with the first and second power modules;
• and
• a control board on which a controller configured to control output currents from the first and second power modules,
• wherein first and second conductor patterns respectively connected with output terminals of the first and second power modules and extending independently of each other are formed in the input and output board, and
• wherein a terminal is mounted on the output connector, the terminal comprising:
• an output terminal portion to be connected to the electric motor;
• and
• first and second board connection portions extending from the output terminal portion to be respectively connected to the first and second conductor patterns.
