摘要： The object of the present invention is to provide an electric contact member characterized by excellent current breaking capacity as well as a high degree of dielectric strength and welding resistance, and the method for manufacturing this electric contact member at a low production cost with high productivity. The above object can be attained by the present invention providing an electric contact member characterized by the texture wherein fire proof metal powder having the form of a flat plate is diffused in the matrix comprising a highly conductive metal, the electric contact member being further characterized in that the flat surface is oriented in one direction and the surface in parallel with the flat surface of the fire proof metal powder is used as a contact point face.
