An environmentally friendly flux for molten steel desulfurization includes CaO and AlOso that [CaO]/[AlO] is within a range of 1.6 to 3.0, and includes one or more alkali metal oxides of NaO, KO, and LiO, and SiOso that [SiO]/[RO] is within a range of 0.1 to 3, [RO] is within a range of 0.5 mass % to 5 mass %, and [SiO] is within a range of 0.05 mass % to 15 mass % in a case in which the [CaO], the [AlO], the [SiO], and the [RO] represent the mass % of CaO, the mass % of AlO, the mass % of SiO, and the total amount of the mass % of NaO, the mass % of KO, and the mass % of LiO respectively.
