<P>PROBLEM TO BE SOLVED: To provide a conductive oxide sintering body capable of properly detecting a temperature in a wide temperature range and indicating a stable resistance value even when it is exposed to a high temperature, a thermistor element using it, and a temperature sensor using the thermistor element. <P>SOLUTION: A conductive oxide sintering body 1 constituting a thermistor element 2 includes a first insulating crystalline phase expressed by RE1<SB POS="POST">4</SB>Al<SB POS="POST">2</SB>O<SB POS="POST">9</SB>, and a second insulating crystalline phase expressed by (RE2<SB POS="POST">1-c</SB>SL<SB POS="POST">c</SB>)(Al<SB POS="POST">x</SB>M1<SB POS="POST">y</SB>)O<SB POS="POST">3</SB>, when an element group of at least one of Yb, Lu and at least one kind of 3A group elements except for Yb, Lu, La is an element group RE, an element group of at least one kind of 3A group elements except for La and including at least one kind of elements constituting the first element group RE1 is an element group M1, an element group mainly including at least Sr among Sr, Ca and Mg at a mole ratio is SL, and an element group of at least one kind of 4A-7A and 8 group elements except for Cr is M1. A coefficient c is 0.18<c<0.50. <P>COPYRIGHT: (C)2012,JPO&INPIT |
