摘要:
There are provided an electronic component metal material which has low insertability/extractability, low whisker formability, and high durability, and a method for manufacturing the metal material. The electronic component metal material 10 includes a base material 11, an A layer 14 constituting an outermost surface layer on the base material 11 and formed of Sn, In or an alloy thereof, and a B layer 13 constituting a middle layer provided between the base material 11 and the A layer 14 and formed of Ag, Au, Pt, Pd, Ru, Rh, Os, Ir or an alloy thereof, wherein the outermost surface layer (A layer) 14 has a thickness of 0.002 to 0.2 µm, and the middle layer (B layer) 13 has a thickness larger than 0.3 µm.
