Abstract
A plurality of fuses (F, F, . . . , and Fn) are respectively disposed on current paths for a plurality of currents branched from one end of a DC power source (). In a blown fuse detection apparatus (), ends on one side of a plurality of capacitors (C, C, . . . , Cn) are respectively connected to the ends on the downstream side of the plurality of fuses (F, F, . . . , and Fn). A plurality of currents that have flowed through the capacitors (C, C, . . . , Cn) are input to a circuit switch () and a circuit resistor (). A microcomputer () instructs that the circuit switch () be switched on, obtains a detected value of a resistance voltage, and detects, based on the obtained detected value, whether or not there is a blown fuse among the fuses (F, F, . . . , and Fn).
