PROBLEM TO BE SOLVED: To provide an engine control unit which inhibits the occurence of problems caused by water, chemicals, vibrations, heat, and noise, etc.SOLUTION: An ECU includes a substantially rectangular printed circuit board 1 on which a microcomputer 21 is mounted. The printed circuit board 1 includes a connector part 2 in which connection terminals 5 are provided at one side edge part formed along a longitudinal direction so as to be aligned. The connection terminals of the connector part 2 are classified by the installation positions. The connection terminals installed at the one longitudinal side serve as input connection terminals 5a and the connection terminals installed at the other side serve as output input connection terminals 5b. In the printed circuit board 1, the microcomputer is disposed at a substantially center part in the longitudinal direction. An electronic component serving as an input interface circuit 22 is disposed at the one longitudinal side, and an electronic component serving as an output interface circuit 23 is disposed at the other side.
