Provided is an engine control unit capable of suppressing the occurrence of problems caused by water , chemicals , vibrations, heat, noise , and the like. An ECU is equipped with a substantially rectangular printed circuit board (1) on which a microcomputer (21) is installed. One lateral edge section of the printed circuit board (1) along the lengthwise direction thereof is equipped with a connector unit (2) in which connection terminals (5) are arranged. The connection terminals of the connector unit (2) are arranged in a manner such that input connection terminals (5a) are located on one side of a setting position in the lengthwise direction while output connection terminals (5b) are located on the other side thereof. The printed circuit board (1) has the microcomputer positioned in the substantially center section in the lengthwise direction thereof. An electronic component is positioned on one side in the lengthwise direction as an input interface circuit (22) , and another electronic component is positioned on the other side as an output interface circuit (23). |
