It provides a material having high ionic conductivity that conducts proton or oxide ions and is excellent in moisture resistance and reduction resistance. As an ion conductor, General formula (1): BaZr a Ce b M 1 c L 1 d O 3 -α (M 1 is at least selected from the group consisting of rare earth, In, Mn, Fe, Co, Ni, Al, and Ga) 1 type, L < 1> is at least 1 sort (s) chosen from the group which consists of P, B, and N, a, b, c, d, and (alpha) are 0 <a <1.2, 0 <b <1.2, 0 <c <1.2, 0.9 <a + b + c <1.2, 0 <d <0.1 and 0 <α <3 are satisfied.) Perovskite oxides are used. |
