Abstract
An in-vehicle device of the present invention includes a fuse and an upstream capacitor having one end connected to a connection node upstream of the fuse in a current path of current that flows through the fuse. One end of a downstream capacitor is connected to a connection node downstream of the fuse in the current path. A determiner determines whether or not the fuse is blown based on an upstream voltage that passed through the upstream capacitor and a downstream voltage that passed through the downstream capacitor.
