CONNECTOR TERMINAL, AND MATERIAL FOR CONNECTOR TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide a connector terminal having a tin layer on the outermost surface and a material for the same, capable of achieving a low insertion force independently of details of a microstructure of the outermost surface and without excessive rise in contact resistance.SOLUTION: In a connector terminal, a composite coating layer consisting of a region where tin is exposed on the outermost surface and a region where a copper-tin alloy is exposed is formed on a basic material surface in a region including a contact part contacted with another conductive member, and a gloss degree of a surface of the composite coating layer is in a range of 50-1000%.
