PROBLEM TO BE SOLVED: To provide a solid wire that is used for multi-pass welding of carbon dioxide shielded arc welding of a thick steel plate, and has a stable arc and less sputter generation even in the welding of a narrow groove joint and a high interpass temperature, and thereby achieving welding to obtain a weld metal of good mechanical performance. ! SOLUTION: The solid wire for gas shielded arc welding of a thick steel plate contains, by mass% to the wire total mass, 0.02-0.08% of C, 0.6-1.5% of Si, 1.5-2.5% of Mn, 0.1-0.4% of Mo, 0.15-0.40% of Cu, 0.1-0.4% of Ti, 0.005-0.030% of Ce, and 0.003-0.010% of B. !
