The specific electrical conductivities of binary molten salts of LiF-NaF and LiF-CaF_2 systems were measured with the following results : 1) The measured specific electrical conductivity of molten lithium fluoride at 900℃ was 8.58 ohm^<-1> cm^<-1> and at 1000℃ was 9.31 ohm^<-1> cm^<-1>. 2) The specific electrical conductivities of LiF-NaF binary molten salt system were measured at 800,900 and 1000℃, Also, LiF-CaF_2 binary molten salt system were measured at 900 and 1000℃. In both of the salt systems, the specific electrical conductivities decrease almost parabolically with the decrease of the molar fraction of lithium fluoride. 3) In both of the binary molten salt systems, measured values of the specific electrical conductivities agreed well with the calculated values obtained according to the "Kuroda's approximated formula" and "Taniuchi's modified formula". Therefore, it was determined that the ionic species of these binary molten salts which take part in the electric conduction are Li^+, Na^+, Ca^<++> and F^- respectively.
