In order to resolve the problems of prior art such as bigger volume of fuse wire structure and higher failure rate of fuse wire cut off, the present invention provides a fuse wire structure comprising: a first metal pad and a second metal pad, disposed on different positions of a first dielectric layer, the first metal pad and the second metal pad define an internal district locating in the firstdielectric layer; and a conductive line, disposed in a second dielectric layer locating under the first dielectric layer, so as to connect the first metal pad and the second metal pad, wherein the conductive line back and forth stretches in the second dielectric layer at least twice under the internal district. The present invention also provides an integrated circuit device containing the fuse structure. The fuse structure of the present invention is easy to be implement without additional other technique, and can further curtail with the curtailment trend of the element size formed in the integrated circuit device.
