Terminal connector and method for producing a terminal connector

Purpose is to provide a terminal connector comprising a silver layer on a surface of an electrical contact portion with a reduced coefficient of friction of the surface and excellent in usability and productivity and a method for producing such a joint connector. A coating layer (4) composed of a layer of silver (2) and a film (3) formed by in contacting the silver layer (2) containing a thiol and benzotriazole solution is formed on a contact portion of a mating connector (20) to be brought electrically connected with another electrically conductive member (29) in contact. A solvent of this solution is preferably water and the thiol is preferably octadecanethiol.
