Zusammenfassung:	A method for producing an Ag-based electrical contacting material by an extrusion is provided to improve productivity yield and reduce a manufacturing cost by decreasing line troubles. A method for producing an Ag-based electrical contacting material by an extrusion includes the steps of: manufacturing a billet. The billet is a circular plate and consists of an Ag alloy part and an Ag part. The Ag alloy part is a cylinder having a circular groove on an exterior thereof. The Ag part is coupled to the circular groove; pre-heating the billet; cladding the billet by extruding the pre-heated billet; and processing the clad billet into a needed size by cool rolling the billet.
