PROBLEM TO BE SOLVED: To solve the problems in which, since a contact material is manufactured by a sintering method and a contact is manufactured by brazing or welding the contact material to a base material, it is not possible to make a contact point long, it is required to produce contact materials one by one, it takes much time and effort to complete a contact, and it is difficult to manufacture contacts of various shapes.SOLUTION: The manufacturing method of a contact comprises processes of: producing a composite contact material by applying a base material surface of a desired shape with either a 1 to 99 mass% Ag-W coating or a 1 to 99 mass% Ag-WC coating so as to keep both sides remained; and continuously producing a plurality of pieces by cutting the composite contact material. |
