Abstract: This wire for gas-shielded arc welding is a wire for joining a plurality of thin steel sheets by gas-shielded arc welding, the wire including, in mass %, with respect to a total mass of the wire: C: 0.06 to 0.15%; Si: more than 0 to 0.18%; Mn: 0.3 to 2.2%; Ti: 0.06 to 0.30%; Al: 0.001 to 0.30%; and B: 0.0030 to 0.0100%, in which Si, Mn, Ti, and Al satisfy Expressions (1) and (2). Si×Mn≤0.30  Expression (1) (Si+Mn/5)/(Ti+Al)≤3.0  Expression (2)
