Abstract
According to an aspect of the present invention, there is provided a sintered electroconductive oxide containing a perovskite phase of perovskite-type crystal structure represented by the composition formula: M1M2M3AlCrOwhere M1 is at least one of elements of group 3A other than La; M2 is at least one of elements of group 2A; M3 is at least one of elements of groups 4A, 5A, 6A, 7A and 8 other than Cr; and a, b, c, d, e and f satisfy the following conditional expressions:0.600≦a≦1.000;0≦b≦0.400;0.150≦c<0.600;0.400≦d≦0.800;0<e≦0.050;0</()≧0.18; and2.80≦f≦3.30.With the use of this conductive oxide sintered body, it becomes possible to carry out proper temperature measurements over the temperature range from a low temperature of −40° C. to a high temperature of 900° C. or higher.
