The invention discloses an electric energy meter with an anti-electricity stealing monitoring function. The PCB of the electric energy meter is provided with a current monitoring module; the current monitoring module is connected with an electricity leakage sensing device; the electricity leakage sensing device comprises a magnetic core ring; a neutral wire and a fire wire pass through the magnetic core ring to be connected onto the electric energy meter; the magnetic core ring is wound with a sensing coil; the sensing coil is connected with the current monitoring module; the current monitoring module can monitor whether electricity leakage exists and sends an electricity leakage signal to an alarming module located on the PCB; and the alarming module can send alarming information. Abnormal signals can be sent timely, the investigation force on electricity stealing finding can be improved, electricity stealing conditions are effectively reduced, and economic loss is retrieved for an enterprise.
