PROBLEM TO BE SOLVED: To improve the wear resistance of a copper based sintered contact material while alleviating attacks on its mating member through scratching-off of local agglutinates on the sliding contact surface, and to improve seizure resistance through restraint of frictional heat generation by a hard phase. SOLUTION: There is provided a copper based sintered contact material in which one or more kinds of intermetallic compounds each comprising two or more elements selected from the group consisting of Ni, Si, Ti, Co, Al, V and P are dispersed and the total amount of the two or more elements selected from Ni, Si, Ti, Co, Al, V and P is within the range of 0.5 to 10 mass%.
