PROBLEM TO BE SOLVED: To provide a manufacturing method for a wire for gas shielded arc welding, which is excellent in the feeding property. SOLUTION: This is the manufacturing method for the wire for the gas shielded arc welding, which is excellent in the feeding property, is characterized in that in a finish drawing process by which the wire is drawn from a prescribed wire diameter to a final wire diameter, which is successive to a primary drawing process, an annealing process is performed succeedingly from primary drawing, the finishing drawing process includes a drawing process in the reverse direction to at least the primary drawing, and the finishing drawing is performed in a way such that the total area reducing factor of each step of the finish drawing either in the same direction or in the reverse direction to that of the primary drawing before a final wire diameter, is set to 25% or over, and the number of steps of the area reducing of the finish drawing, is set to three times or over, the ratio of a kinetic friction factorμ(a) in the longitudinal direction A of the wire to a kinetic friction factorμ(b) in the longitudinal direction B reverse to the longitudinal direction A is set to (μ)(a)/μ(b)>=1.07.
