<P>PROBLEM TO BE SOLVED: To provide an electrical contact and a connector terminal, capable of suppressing increase of contact resistance resulting from a slide and holding stable contact resistance, even when applying a lubricant in order to reduce wear of a contact in the slide. <P>SOLUTION: The electrical contact includes: a contact part surface of one contact formed with a metal including silver as a main component; a contact part surface of the other contact formed with a metal including a copper gallium compound as a main component; and at least one of the contact part surfaces formed by application of a lubricant. A base material for forming the contact is copper or a copper alloy. The copper gallium compound is CuGa<SB POS="POST">2</SB>. The connector terminal includes: a contact part surface of one terminal formed with a metal including silver as a main component; a contact part surface of the other terminal formed with a metal including a copper gallium compound as a main component; and at least one surface of the two terminals in a fitting part formed by application of the lubricant. <P>COPYRIGHT: (C)2012,JPO&INPIT |
