The utility model discloses a heating body for electric heater relates to PTC heating body technical field, including one -sided two -pole PTC element, conducting wire and insulating seat body. One -sided two -pole PTC element has electrode face, and electrode face is equipped with the first electrode and second electrode of interval distribution, and two conducting wires are respectively through the electric connection of welding mode with the first electrode and second electrode. Insulating seat body 3 has the cavity of bottom closed, and one -sided two -pole PTC element of welding conducting wire is set up in the cavity with the direction of electrode face downward, and the first electrode is completely buried with second electrode in the cavity. The utility model discloses by adopting one -sided two -pole PTC, and two electrodes are located same electrode face, and electrode area reduces about two -thirds, and the use amount of silver is reduced greatly, and cost is saved, can simultaneously weld two conducting wires, and production efficiency improves one time, can ensure two welding spots when assembling and completely place in the cavity bottom of ceramic seat body, make all electrified components deep bury in insulating seat body, and the risk of breakdown is eliminated.
