Abstract
A vehicle-mounted semiconductor switch device includes a semiconductor switch that is controlled by an ON signal and an OFF signal output from an vehicle-mounted drive circuit and that is switched between an ON state and an OFF state between a first conductive path and a second conductive path. The vehicle-mounted semiconductor switch device further includes a voltage detection unit. The semiconductor switch includes a first lead portion electrically connected to the first electrode, and a conductor portion electrically connected to the first electrode. One of the conductor portion and the first lead portion is bonded to the first conductive path, and the other is bonded to a first voltage detection path. A voltage detection unit detects a voltage applied to the first voltage detection path.
