Abstract
Provided is a crimp terminal designed to be crimped onto an end portion of an electric wire to form a terminal-equipped electric wire, achieving both of ensuring mechanical strength of the terminal-equipped electric wire and reducing a contact resistance between the electric wire and the crimp terminal. The crimp terminal comprises an electric contact section and an electric-wire crimp section to be crimped onto a conductor in the end portion of the electric wire, the crimp terminal being formed of a metal plate which has a copper-containing plate body and a tin-plating layer covering a surface of the plate body. In the crimp terminal, the tin-plating layer has a smaller thickness in a crimp surface region where the electric-wire crimp section is to make contact with the end portion of the electric wire is less than that in an electrical contact surface region where the electric contact section is to make contact with a counterpart terminal.
