）。Electrical connection terminals used in connectors, relays, switches, etc. are required to have both high conductivity and high elasticity due to their nature. However, no metal material is currently known that satisfies these two requirements at the same time. Therefore, the present inventors have proposed an electrical connection terminal forming material in which a conductivity-imparting metal layer with high conductivity and a spring-imparting metal layer with excellent spring properties are laminated with a plastic layer interposed therebetween (for example, (See patent application No. 59-139499).

る。(Operations and Effects of the Invention) As is clear from the above description, in the present invention, the contact area is provided with a protrusion to reduce the contact area.
Of course, it is possible to prevent the contact pressure per unit area from decreasing, but it can also be increased. Therefore, as the electrical connection terminal with a multilayer structure becomes smaller, the reliability of the connection, that is, the reliability of the connection that depends on the contact pressure, increases. Sexual decline can be easily prevented.
