PROBLEM TO BE SOLVED : To properly control a thermal expansion coefficient while achieving high conductivity in a conductive oxide sintered body. SOLUTION : A conductive oxide sintered body comprises a crystal phase having a perovskite type oxide crystal structure represented by compositional formula : REaCrbFecNidOx (where, RE is a rare earth element, a+b+c+d=1, 1.3≤x≤1.7). The coefficients a, b, c, and d satisfy 0.459≤a≤0.524, 0
