PROBLEM TO BE SOLVED: To provide a measuring instrument for a vehicle which achieves space saving and yet is able to supply electric power to an external device.SOLUTION: A measuring instrument for a vehicle includes: a liquid-crystal display panel which utilizes electric power from an on-vehicle battery B to display vehicle information; an overvoltage protection circuit 4 provided between the on-vehicle battery B and the liquid-crystal display panel; and a DC/AC conversion circuit 9 which utilizes electric power of the on-vehicle battery B, which is supplied through the overvoltage protection circuit 4, to supply electric power to an external device D. The measuring instrument for the vehicle includes these components in the same case.SELECTED DRAWING: Figure 1
