Glass composition, glass frit containing same, glass paste containing same, and electrical/electronic component obtained using same

An electrical component having a sealing unit comprising a lead-free glass phase, wherein

• the sealing unit comprises 50 to 100 vol % of the glass phase, and
• the glass phase comprises 10 to 60 mass % of Ag2O, 5 to 65 mass % of V2O5 and 15 to 50 mass % of TeO2 when the components are represented by oxides,
• wherein the total content ratio of Ag2O, V2O5 and TeO2 is 75 mass % or more and less than 100 mass %,
• the glass phase further comprises one or more selected from the group consisting of P2O5, BaO, K2O, WO3, Fe2O3, MnO2, Sb2O3 and ZnO as a remnant by more than 0 mass % and 25 mass % or less, and
• wherein (content ratio of Ag2O)/(content ratio of V2O5) is 2.6 or less.

An electrical component having an electrode or wiring comprising a lead-free glass phase and metal particles, wherein

• the electrode or wiring comprises 5 to 30 vol % of the glass phase and 70 to 95 vol % of the metal particles,
• the metal particles are silver, a silver alloy, aluminum, an aluminum alloy, copper or a copper alloy, and
• the glass phase comprises 10 to 60 mass % of Ag2O, 5 to 65 mass % of V2O5 and 15 to 50 mass % of TeO2 when the components are represented by oxides,
• wherein the total content ratio of Ag2O, V2O5 and TeO2 is 75 mass % or more and less than 100 mass %, and
