To provide a control device for a vehicle capable of setting a control specification without depending on an other control unit and easily controlling a control circuit board.

In this concentrated switch unit (on-vehicle control device) 1, a circuit 10 for outputting a control signal to an on-vehicle device is provided, and the control circuit board 4 formed with a plurality of screw holes 21 to 23 is fixed to an exterior case body 3 by a screw member N having conductivity. The plurality of screw holes 21 to 23 are formed on the circuit 10. The circuit 10 is made conductive by the screw member N passing through the screw holes 21 to 23. By the presence or absence of the screw member N, a wiring pattern is changed.
