<p>PROBLEM TO BE SOLVED: To provide a connector contact material free from the generation of discoloration in appearance after aging, excellent in solderability and further excellent in slidability and to provide its production method. SOLUTION: In this connector contact material, the surface of an electrically conductive base material 1 is formed with a Cu-containing Sn plated layer 2, the surface of the Cu-containing Sn plated layer 2 is the treated face by benzotriazole or the derivative thereof, and also, when the surface is subjected to AES analysis, the thickness of the benzotriazole or the derivative thereof measured as C reaches 0.0003 to 0.01μm.</p> |
