In order to obtain a resistor which is excellent in acid resistance by allowing a thick-film resistance body paste for use in a resistance body to be lead-free and is capable of simultaneously firing 3 layers of an electrode portion, a resistance portion and a surface coat portion all together at a time and can also contribute to global environment, provided is a resistor, having a substrate (1), a resistance body (3), an electrode (2) connected to the resistance body (3) and a precoat (4) covering the resistance body (3), in which a thick-film resistance body paste which contains, as main components, electrically conductive powder, a glass frit and an organic vehicle, in which the glass frit is constituted by a composition containing, in percentages by weight, 1% or less of alkali metal, from 10 to 30% of Bi2O3, from 25 to 40% of SiO2, from 30 to 40% of BaO, from 5 to 7% of ZnO, from 4 to 7% of Al2O3 and from 0.01 to 8% of B2O3, and does not contain PbO is used for forming the resistance body002E <IMAGE>
