▎ 摘　　要

NOVELTY - The terminal (20) has a conductor connecting portion (210) which is provided to be electrically connected to a conductor (151) of an electric wire (150). A terminal connecting portion (220) is provided to be electrically connected to an opposite terminal. A graphene film is provided to be arranged between the first surface and the conductor of the electric wire when the conductor of the electric wire is electrically connected to the conductor connecting portion when the first metal material and a third metal material forming the conductor of the electric wire have different ionization tendencies. The graphene film is provided to be arranged between the second surface and the surface of the opposite terminal when the opposite terminal is electrically connected to the terminal connecting portion when the second metal material and a fourth metal material forming a surface of the opposite terminal have different ionization tendencies. USE - Terminal e.g. female terminal and male terminal, used in electric wire of electric connection unit (all claimed). ADVANTAGE - The increase in manufacturing costs of the female terminal is prevented, the degree of freedom in designing the female terminal is improved, and the miniaturization of the female terminal is facilitated. The galvanic corrosion is prevented by providing the graphene film only to the female terminal without changing the material or plating treatment method of the male terminal installed in the apparatus. The increase in size of the terminal is prevented or reduced. The decrease in the crimping strength of the conductor connecting portion due to heating and the decrease in the elastic force of the elastic portion due to heating are prevented. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electric wire with terminal. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of an electric connection element in which a female terminal and a male terminal are connected to each other.
