A resistor having a resistor layer on a substrate, obtained by forming on the substrate a resistor paste including a glass material substantially not containing lead but containing CaO and B2O3, a conductive material substantially not containing lead, and an organic vehicle, then, firing at a temperature of 830 to 870° C. for 5 to 15 minutes; wherein, when observing a section along the thickness direction of the resistor layer with a transmission electron microscope (TEM), an occupying area of a crystal substance CaB2O4 precipitated in the resistor layer of the observation section is less than 30.0% of an area of the resistor layer of said observation section. According to the invention, it is possible to provide a lead-free resistor having a high resistance value and a short time overload (STOL).
