Disclosed herein is a flux cored wire for gas shielded arc welding which comprises a seam section for improving the rectilinear property of the wire, thereby preventing the occurrence of bead meandering. The flux cored wire for gas shield arc welding is manufactured by forming a metal sheath, packing the inside of the metal sheath with a flux, followed by forming into a metal pipe shape and wire drawing and satisfies Relationship (1) below: 1.4<=(Rrcts/Ructs)<=4.0 (1) wherein Rrcts represents the range of tensile strength of real cross section (real tensile strength range in a state where the flux is packed), and Ructs represents the range of tensile strength of unpacked cross section (real tensile strength range in a state where the flux is unpacked).
