A QQ-type spirakore is made by winding a silicon steel strip or a non-crystal magnetic strip into an inner ring egg-shape spirakore embryo, and then cutting a middle section of the egg-shape spirakore embryo into two symmetric assembling bocks, so as to fix the two assembling blocks into a coil structure of a power factor corrector in a butted way. In addition to largely reduce a waste of material, the film-like QQ-type spirakore structure can also effectively reduce ill products. The magnetic crystal generated is a non-orientation structure, and the egg-shape spirakore is a structure without angles, which facilitate a guidance of air flow and a reduction to an unusual tone and low frequency ripple interference.
