In an electronic control unit for controlling operation of various devices, a circuit board carrying electronic components thereon and a connector for connecting the control unit to outside devices are electrically connected through a flexible printed-circuit sheet. A casing of the control unit is designed to contain therein a circuit board selected from variously sized circuit boards. The circuit board may be functionally divided into a certain number of circuit boards. Some varieties of each functionally divided circuit board are prepared, and circuit boards meeting a particular requirement are selected from the varieties and used in a control unit. Thus, the electronic control units meeting various requirements are efficiently and economically manufactured.

Ribs are unitarily formed on an outer wall surface of a casing to compensate for an inclination of an inner wall surface corresponding to a draw angle provided for molding the inner wall surface. The direction of pins of a casing connector which connects an electronic control circuit of a printed circuit board accommodated within the casing to external wiring coincides with the direction of insertion of a checker connector. Alternatively, a protrusion or recess may be formed on a jig device on which the casing is placed for connection to an operation checking apparatus.
