A solid wire is provided to control increase in welding cost to the minimum, and to have excellent stability of wire feed, burn-through resistance, undercut resistance, and crack resistance while slag and spatter are hardly generated. A solid wire used for arc welding comprises C: 0.005 to 0.080 mass percent, Si: 0.30 to 1.20 mass percent, Mn: 1.15 to 1.65 mass percent, and S: 0.050 to 0.200 mass percent. The solid wire is controlled to contain P: 0.017 mass percent or less, O: 0.0070 mass percent or less, and N: 0.0050 mass percent or less respectively, in which (content of C)+{(content of P)*5}<=0.135 mass percent is satisfied, and the solid wire being further controlled to contain as impurities Ti 0.15 mass percent or less, Zr 0.10 mass percent or less, B 0.0050 mass percent or less, and Cr, Ni, Nb, V, La and Ce 0.20 mass percent or less respectively, wherein amount of oil adhered on a surface of the relevant solid wire is controlled to be 1.2 g or less per wire of 10 kg.
