摘要

Problem to be solved: to provide a conductive material which is small in electrical resistivity and excellent in TCR (resistance temperature coefficient) property and has a low precious metal content.General formula (1): ca1-acu3-bru-4-xmnxo12 - δ（ 1) (1)0 ≦ a ≦ 0.10 ≦ B ≦ 0.30 ≦ x ≦ 2.00 ≦ δ A complex oxide represented byOr an oxide represented by the general formula (1) and an oxide of CuWhen the sum of the composite oxide represented by the general formula (1) and the oxide of Cu is 100% by volume,The content of the composite oxide represented by the general formula (1) is 25 vol% or more and less than 100% by volume;The content of the Cu oxide is greater than 0 volume% and less than 75% by volume;Features a conductive material.Diagram
