PROBLEM TO BE SOLVED: To provide a probe pin which achieves a lager bending strength and a higher electric conductivity. SOLUTION: A copper-silver alloy is used with the silver content thereof of 1 to 25 atomic % to hold the tensile strength thereof in the range of 1,000 to 1,500 MPa while the electric conductivity is specified in the range of 60-90% IACS. In the probe pin 1 comprising a straight part 2 and a tapered part 3, the crack and breaking of a bent part 4 as caused by the bending work of the pin tip can be prevented as much as possible.
