The electrical properties of V_2O_5-P_2O_5 system and V_2O_5-P_2O_5-Na_2O system glasses were studied in this paper. These glasses were semiconducting ones that were electronic conductors. The 17 kinds of glasses of above system were melt for approximately 4 hr. at about 1300℃ in electric furnace. The fused glasses were ground into disk of 1 mm thickness and approximately 2cm diameter. Thin silver film of 1cm diameter curcle was evaporated on the glass surface. The resistivity of these samples were measured in the range of 60℃-300℃ by TAKEDA-RIKEN Electrometer. (10)^<14> input impedance) The conclusions were as following. (1) The resistivity of the glasses decreased with rising of temperature and log of the resistivity was linear function of reciprocal of the temperature. (2) The activation energy was 13-27 kcal/mol and decreased rapidly with increasing of the concentration of V_2O_5. (3) The resistivity decreased with the concentration of V_2O_5. Log of the resistivity was related linearly to log of V_2O_5 mol% and the slope of this line was 4.3.
