Abstract
A sensor unit includes a current sensor that detects a current, a voltage sensor that detects a voltage, a ground fault sensor that detects a ground fault, and a common substrate on which the current sensor, the voltage sensor, and the ground fault sensor are mounted. In the sensor unit, for example, in a power supply circuit of a vehicle, the three sensors of the high voltage system can be integrated on the common substrate, so that an increase in the number of parts can be suppressed.
