PROBLEM TO BE SOLVED: To provide a safe electric warmer which uses a heater wire that can prevent magnetic field leakage and can prevent a danger by cutting off an electric current immediately in an abnormal heating temperature, and which can be connected to a controller connector of a current electric warmer. SOLUTION: On an electric warmer, a heater wire is formed by laminating an inner heating wire and an outer heating wire in which a current flows in a direction reverse to that of a current flowing in the inner heating wire, and a signal line is provided with the heating wire, and top end terminals of an inner heating coil and an outer heating coil are connected, and two terminals of a three-terminal connector connecting the inner heating coil and the outer heating coil are arranged at both sides of the three-terminal connector, and a terminal connected with the signal line of the three-terminal connector is arranged adjacent to one of the two terminals, and a bridge to which a one-terminal connector is fitted at a prescribed interval between the other terminal of the two terminals and the terminal connected with the signal line is formed, and the one-terminal connector is fitted to the bridge.
