An anti-fuse element that includes first and second electrode films on both of upper and lower surfaces of a dielectric film to form an element body. When an operation voltage is applied to the element body, the first and second electrode films are fused by heat generation by electrification, whereby balled portions are formed, and a crack also occurs in the dielectric film. Then, the balled portions are enlarged, the dielectric film is completely divided, and the first and second electrode films are welded and integrated with each other in a mode of tangling end portions of the dielectric film, and form bonded portions that turn the anti-fuse element into a conducting state.
