PROBLEM TO BE SOLVED: To provide a flux cored wire for high corrosion resistant austenic stainless steel, being a welding material which has corrosion resistance higher than high corrosion austenic stainless steel such as SUS317J5L, is superior in structure stability, is very inexpensive in comparison with a Ni group alloy welding material, and is capable of high efficient welding operation. SOLUTION: This wire, wherein flux is filled in a metal outer shell, includes, against wire total weight in the metal outer shell and the flux, 0.030 wt.% or less C, 0.1-1.5 wt.% Si, 0.1-1.5 wt.% Mn, 0.015 wt.% or less P, 0.005 wt.% or less S, 18.0-43.0 wt.% Ni, 18.0-25.0 wt.% Cr, 2.0-9.0 wt.% Mo, 1.0 wt.% or less Ti, 1.5 wt.% or less Cu, 0.10-0.25 wt.% N, and the balance of slag forming components and Fe.
