<P>PROBLEM TO BE SOLVED: To provide a full-wave rectifying circuit capable of preventing abnormal heat generation or damage to circuit components due to overcurrent applied to a power supply line of either of half-wave rectifying circuits when only the fuses of provided on a power supply line of the other half-wave rectifying circuit are disconnected. Ž<P>SOLUTION: When a blown fuse detecting circuit 11 detects disconnection of fuses 2a, 2b provided on the power supply line of one half-wave rectifying circuit L1, a control circuit 10 controls each of relay driving circuits 3a-3c so that relay contact points provided on the half-wave rectifying circuits L1, L2 can each open, and a current flowing through the power supply line of each of the half-wave rectifying circuits L1, L2 can be interrupted.
