The invention provides an electric leakage indicating device of an electric leakage circuit breaker, and mainly solves the problems of an existing electric leakage indicating device that the assembling process is complex, the vibration resistance is poor, and the stability is poor. The electric leakage indicating device comprises a base, an electric leakage tripper, a handle, an electric leakage indicating member and a push rod. A positioning boss extending to the other side of the base is arranged on the handle. The electric leakage indicating member comprises an indicating block, a driving boss and a limiting boss. The limiting boss is provided with a first position arranged on one side of the positioning boss when the state is indicated to be normal, and a second position arranged on the other side of the positioning boss when an electric leakage is indicated. The electric leakage indicating device has the advantages that compared with the existing indicating device, the number of components is smaller, the assembling is simplified, and the cost is lowered; in addition, by means of the mutual cooperation between the positioning boss on the handle and the limiting boss on the electric leakage indicating member, the position locking of the electric leakage indicating member under different states is realized, and the reliability of electric leakage indicating is further improved.
