摘要： 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.

摘要： Provided is an electrical contact material that can suppress an increase in contact resistance even if contact pressure with a counterpart material is small. An electrical contact material that includes a base material made of metal, a metal layer provided on a surface of the base material, and an oxide layer provided on a surface of the metal layer. The metal layer is made of metal that contains zinc, copper, and tin, the oxide layer is made of an oxide that contains zinc, copper, and tin, and beneath the oxide layer, a ratio of the atomic concentration of copper to the atomic concentration of tin is less than 1.4.

摘要： A terminal-equipped wire is provided with a wire including a conductor, a terminal to be connected to the conductor, and a shell to be mounted on the terminal. The terminal includes a grip portion for sandwiching the conductor. The shell includes a pressing portion for pressing at least a part of the grip portion toward the conductor. The grip portion has a Sn—Ni alloy layer. The Sn—Ni alloy layer includes locally projecting protrusions. The protrusions bite into the conductor.

摘要： The electrical contact material includes a base material, a coating layer provided on a surface of the base material, and an oxide layer provided on a surface of the coating layer. The base material contains Cu. The coating layer includes an undercoat layer, a first layer, and a second layer that are provided in that order from the base material side. The undercoat layer contains Ni. The first layer contains Ni, Zn, Cu, and Sn. The second layer contains Sn. The oxide layer is constituted by an oxide containing Zn, Cu, and Sn. The undercoat layer has a thickness larger than 0.5 μm.
