PROBLEM TO BE SOLVED : To provide a fiber whose electric resistivity changes in response to temperature, to provide a fiber structure; and to provide a fiber product. SOLUTION : This fiber is characterized by containing fine particles changing their electric resistivity in response to temperature, such as a perovskite oxide represented by a chemical formula, A1-xBxMnO3, and containing Mn, in the fiber. Therein, A is at least one of rare earth element ions of La, Pr, Nd, and Sm, and B is at least one of alkaline earth metal ions of Ca, Sr, and Ba. COPYRIGHT : (C)2007, JPO&INPIT
