The invention provides a left-right parallel loop bipolar electrode. At its front-section part, a metal sleeve and a rigid tube are arranged in parallel at an interval on left and right, two insulating tubes are fixed at heads of the metal sleeve and the rigid tube respectively, one end of a positive electrode is connected with a wire, led from the rigid tube, with an insulating layer in the corresponding insulating tube, and another wire with an insulating layer is welded with the metal sleeve. At its rear-section part, a tail end of the metal straight tube is connected with a binding post, the binding post is connected with a double-core wire, and the two wires with the insulating layers penetrate through the metal straight tube to be correspondingly connected with the double-core wire respectively； the other end of the positive electrode is fixed in the other insulating tube.
