PURPOSE: An electric heating mat is provided to reduce manufacturing costs by reducing the number of connection lines connected to a controller and the number of connection terminals of a connector. CONSTITUTION: An electric heating mat includes a mat(10), a switching means(S), a connector(20) and a controller(30). The mat includes a heating line(11) generating heat and a temperature sensor(12). The switching means switches the connection of a sensing signal line and the heating line in the inside of the mat. The connector includes a plurality of connection terminals(21a,21b,21c) respectively connecting one end, other end and a ground line of the heating line and a signal transceiver(22). One end of the controller is connected to the connection terminal of the controller through 3 strands connection lines(31). Other end(30b) of the controller is connected to an outlet. |
