Document Type and Number:
WIPO Patent Application WO/2014/129221
Kind Code:
A1
Abstract:
Provided are: a metal member which has improved copper and copper alloy laser weldability, and a small heat-affected zone; a terminal and an electric wire connection structure formed using the metal member; and a method for manufacturing the terminal. As shown, for example, in fig. 1, this metal member (1) has: a base material (2) comprising copper or a copper alloy; a white metal layer (3) provided on a part of or the entirety of the base material (2); and an oil film (4) provided on the white metal layer. In the metal member (1), the thickness of the white metal layer is 0.01-0.80 µm, the arithmetic average roughness (Ra) of the surface of the white metal layer is 0.6-1.2 µm, and moreover the electrical double layer capacitance of the oil film is 1.5-7.0 µF/cm2.
