The present invention relates to dephosphorizing flux to adjust a phosphorus component included in molten metal. According to the present invention, the dephosphorizing flux comprises a main raw material including BaCO_3 and a sub-raw material. The sub-raw material includes a first raw material including any one from NaHCO_3 or Na_2CO_3, and a second raw material including CaF_2. According to one embodiment of the present invention, the dephosphorizing flux is able to prevent clogging of a bottom-blown nozzle blowing a carrier gas during dephosphorization while increasing a dephosphorization rate by the dephosphorizing flux. Moreover, unlike the conventional dephosphorizing flux, a substance harmful to environments is not used, thereby being able to reduce risk in environmental pollution and solving expense stress in accordance with environmental pollution prevention facilities and harmful substance management.
