PROBLEM TO BE SOLVED: To provide an improved flux-containing wire for stainless steel welding excellent in posture weldability such as vertical welding, overhead welding, etc., and stability of arc and further brings less spatter. SOLUTION: The slug in a flux is chiefly composed of 0.2-1.2 % of SiO2, 0.2-0.9% of ZrO2, 4.0-6.0 % of TiO2 in mass to the total wire weight. And in such a flux that the sum weight of slug components ranges 5.4-8.4% to the total wire weight is filled by 18-25 % in the outer skin of the stainless steel wire to form the flux-containing wire, Ti (ferrotitanium is shown by Ti converted value) composed of metallic titanium and ferro titanium is contained by 0.3-0.9% to the total wire weight, and the ratio is 20-60% of metallic titanium and 40-80% of ferro titanium.
