An offset electrode 3-time discharging spark plug is disclosed. The invention aims to solve the problems of an existing spark plug that the misfire rate is high and only one flame center is generated during discharging. The technical scheme used to solve the problems and provided by the utility model is characterized in that 3 strip-shaped areas on the top part of the spark plug and the lateral part of one side far away from an offset electrode are sprayed with a conductive ceramic to form conductive bars, the electrode is connected with the conductive bar nearest to the edge, so that a 3-time discharging channel is formed; and the conductive ceramic on the lateral part and a metal housing form a loop. The spark plug can realize a general sparking function; because of the characteristic of the ceramic material and a special shape of the electrode, multiple beams of discharging sparks with a large scope and large intervals can be generated during the discharging; the 3-time discharging is achieved simultaneously, so that the burning speed of a combination gas is accelerated, and explosive power of an engine is increased; and the spark plug is especially suitable for igniting a thin combination gas, and the energy saving effect is obvious.
