<P>PROBLEM TO BE SOLVED: To provide a metallic material for electronic components, which has low insertion and removal resistance, low whisker generation property and high durability, and a method for producing the same. <P>SOLUTION: The metallic material 10 for electronic components is provided with: a base 11; a layer A 14 that constitutes the outermost layer of the base 11 and is formed of Sn, In or an alloy of these elements; and a layer B 13 that is arranged between the base 11 and the layer A 14 so as to constitute an intermediate layer and is formed of Ag, Au, Pt, Pd, Ru, Rh, Os, Ir or an alloy of these elements. The outermost layer (the layer A) 14 has a thickness of 0.002-0.2 μm, and the intermediate layer (the layer B) 13 has a thickness of 0.001-0.3 μm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
