The invention relates to a novel and recoverable thin thermal fuse structure, which is specifically suitable for protecting circuits of mobile phone batteries. The novel and recoverable thin thermal fuse structure comprises two conducting pins, an insulating upper cover and an insulating lower cover; meanwhile, the structure is provided with an arc bimetallic strip, which is an arc strip formed by welding the two ends of at least two layers of metal sheets with different thermal deformation temperatures; the two ends of the bimetallic strip are contacted with the conducing pins so as to form serial connection; the middle top of the bimetallic strip resists to the insulating upper cover, so that the bimetallic strip is fixed in a sealing environment formed by the insulating upper cover and the insulating lower cover; and a fuse, of which the total thickness is not greater than 1.0mm, is formed. The fuse provided by the invention can be used repeatedly; and compared with the traditional fusing fuse, the fuse provided in the invention saves the using cost. In addition, the long-time welding technology can be adopted; and the requirements on the processing condition are greatly reduced.
