PROBLEM TO BE SOLVED: To provide a steel wire for carbon dioxide gas shielded arc welding which improves the stability of ark, the strength of weld metal and the toughness compatibly at a low cost by reducing slag loss of deoxidizing element, and to provide a welding method using the wire. SOLUTION: This wire for carbon dioxide gas shielded arc welding has a composition consisting of, by mass, 0.005-0.20% C, 0.05-0.65% Si, 0.80-1.80% Mn, 0.015-0.100% rare earth elements, 0.05 to 0.20% one kind of Ti, Zr and Al, or 0.05 to 0.20% in total two kinds or more thereof.
