ABSTRACT:
A glass composition for a thick-film resistor including at least one oxide selected from CaO, SrO, and BaO in an amount of 13 mol % to 45 mol %, B2O3in 0 to 40 mol % (however, not including 0), SiO2in 17 mol % to 72 mol % (however, not including 72 mol %), ZrO2in 0 to 10 mol % (however, not including 0), and at least one oxide selected from Ta2O5and Nb2O5in 0 to 10 mol % (however, not including 0), a thick-film resistor paste obtained by mixing this glass composition with a conductive material and organic vehicle, a thick-film resistor obtained by printing and firing this paste and thereby being lead-free, superior in TCR and STOL, and high in resistance, and an electronic device having this thick-film resistor.
