It is aimed to provide a connector terminal including a tin layer on an outermost surface and a material therefor which achieves a low insertion force without depending on the detail of the microstructure of the outermost surface and excessively increasing a contact resistance. A composite coating layer including areas where tin is exposed and areas where a copper-tin alloy is exposed on an outermost surface is formed on a surface of a base material in an area including a contact portion to be brought into contact with another electrically conductive member and the glossiness of the surface of the composite coating layer is in a range of 50 to 1000%. |
