Abstract: A Ti-base wire rod for forming molten metal excellent both in rod Seeding smoothness and arc stability is disclosed. A wire rod 301 is composed of Ti metal, and has in the surficial portion including the surface thereof an oxygen enriched layer having an oxygen concentration higher than that in an inner portion. Ratio Tw/Dw of the thickness Tw of the oxygen enriched layer and the diameter Dw of the wire rod is adjusted within a range from 1null10null3 to 1null10null1, and the average oxygen concentration of the oxygen enriched layer is adjusted to 1 wt % or above.
