  • Patent number: 11843194
    Abstract: A terminal-equipped electric wire includes an electric wire that includes a conductor, a terminal connected to the conductor, and a shell attached to the terminal. The conductor has a nominal cross-sectional area of 0.13 mm2 or less. The terminal includes a grip portion that pinches the conductor. The shell includes a pressing portion that presses at least a portion of the grip portion toward the conductor. At least one of the conductor and the grip portion includes a tin layer, and an oxide coating formed on the surface of the tin layer. An adhering portion formed of a portion of tin contained in the tin layer that passes through the oxide coating and pours out onto a surface of the oxide coating. The adhering portion has an area of 0.100 mm2 or more.
