To provide an earth leakage breaker making readily visible a display in occurrence of earth leakage.

An earth leakage detection block 2 includes an interlocking lever 18 driven by moving a mover 24 by an electromagnetic mechanism 17 in detecting earth leakage to forcibly open a circuit break block, an energizing spring 20 energizing an earth leakage display member 19 in a direction that a display part 19f displaying an earth leakage detected state rotates to a position facing a window hole 25, and a latch member 21 which is disposed to be movable back and forth interlocking with the opening and closing operations of the circuit break block and is moved toward a rear surface side when closed, and onto which a display part 19e displaying an earth leakage not-detected state latches against energizing force of the energizing spring 20 in a state that the earth leakage display member 19 is rotated to a position facing the window hole 25 such that when opened with no detection of earth leakage, movement toward the front surface side is restricted by the mover 24 to keep a latched state and when the earth leakage is detected, restriction on the movement toward the front surface side by the mover 24 is released to release the leakage display member 19 from a latched position.
