Claim 7:
8. A method for manufacturing a probe pin using a Pd alloy for electric and electronic devices, the method comprising providing a probe pin shape using a Pd alloy material for electric and electronic devices that has been processed into a wire shape so that a cross-sectional reduction rate becomes 50% or more and 95% or less in the final plastic processing during plastic processing a Pd alloy for electric and electronic devices having a composition consisting of:
50.0 mass % or more and 55.5 mass % or less of Pd,
6.3 mass % or more and 16.1 mass % or less of Ag,
30.0 mass % or more and 38.0 mass % or less of Cu, and
0.5 mass % or more and 2.0 mass % or less of In,
with the balance being unavoidable impurities;
heat-treating the probe pin shape at a temperature of 350° C. or more and 550° C. or less to adjust a Vickers hardness to 300 HV or more and 480 HV or less and a specific resistance to 6.0 μΩ·cm or more and 8.0 μΩ·cm or less.
