Provided is an alloy-plate-coated material (100) which comprises a base material (10) and an alloy plating layer (20) that is formed on the base material (10) and therefore constitutes an outermost surface layer and comprises an M1-M2-M3 alloy (wherein M1 represents at least one element selected from Ni, Fe, Co, Cu, Zn and Sn; M2 represents at least one element selected from Pd, Re, Pt, Rh, Ag and Ru; and M3 represents at least one element selected from P and B), wherein the molar ratio of M1 to M2 (i.e., M1/M2) is 0.005 to 0.5 in the alloy plating layer (20). |
