PROBLEM TO BE SOLVED: To provide a flux cored wire for gas shielded metal arc welding in which welding working efficiency is improved by excellent welding workability in the all positions welding and which gives stability to a welded structure by holding high tensile strength, and at the same time, an impact absorbing energy. SOLUTION: As chemical components constituting the flux of the flux cored wire for the gas shielded metal arc welding, the sum of the three components Si, Mg, and Al among metals and ferroalloy components having a function of a deoxidizer is 0.5-1.5% to the total weight of the wire, the ratio of Mn to (Mg+Al) among the metals and the ferroalloy components having the function of the deoxidizer, that is, the value of Mn/(Mg+Al), is 3.5-5.0, and the sum of the two or more components selected from a group comprised of Cr, Ni, Mo, and Nb is optimized to 1.0-2.5% to the total weight of the wire.
