The present invention provides a method for producing a contact member being employed in electric/electronic circuits. The method comprises a first process and a second process. The first process comprises a step 1 - 1 for supplying a spring base strip 1 , a step 2 - 1 for supplying a noble metal wire 2 , a seam welding step 3 - 1 for welding and combining the metal wire 2 with the spring base strip after the spring base strip 1 and the noble metal wire 2 held together; and a step 4 - 1 for winding a welded and combined product. The second process comprises a step 5 - 1 for punching the welded and combined product. The seam welding step 3 - 1 comprises a step 6 - 1 for setting welding conditions and a step 7 - 1 for circulating chilled water in a closed channel. A testing step 8 - 1 comprises a sub-step 8 - 1 a for determining a preciseness of a welded portion and a sub-step 81 b for determining a welded strength, is performed between the seam welding step 3 - 1 and the winding step 4 - 1.
