This application relates to a frictional electricity generator increasing output transfer efficiency. In one aspect, the frictional electricity generator includes a housing and a power generation element which is arranged in the housing and in which a + position pole and a − position pole are arranged according to the movement of a positive charge and a negative charge by friction. The + position pole and the − position pole of the power generation element may be arranged at a distance of a predetermined angle on a plane so as to minimize energy loss due to mutual repulsion, and may be connected to each transmission path.
