In a protective device fuses are respectively provided in three current paths from a battery to respective loads. A microcomputer outputs, to a synthesis circuit, pulse signals having pulses in mutually-different positions. The pulse signals correspond to the fuses, respectively. The synthesis circuit synthesizes a pulse signal corresponding to a fuse, among the fuses, that has a voltage on a downstream-side end less than a threshold. The microcomputer identifies a blown fuse on the basis of a synthesized signal synthesized by the synthesis circuit.
