| 摘要 |
An object of the invention is to provide a process for providing a connector, which prevents component atoms constituting a material and a substrate layer from diffusing into a tin-containing material layer and suppressing an occurrence of external force-type whiskers upon the application of external force to a surface of the tin-containing material layer, and a connector produced by the same process. In a production process of a connector comprising a step of providing a substrate layer on a surface of the material to surface treat the material and a step of providing a tin-containing material layer on an upside of the substrate layer to surface treat the substrate layer, the object can be achieved by further comprising a step of providing a barrier intermediate layer before the provision of the tin-containing material layer.
