To provide a method of manufacturing thick-film resistor elements that forms thick-film resistors having a uniform thickness on a substrate surface with high precision. A method of manufacturing thick-film resistor elements by applying a thick-film resistor composition, obtained by dispersing a conductive component and an inorganic binder in an organic medium and which has a specified rheology, through a clear relief image obtained by exposing, curing, and developing a resist layer of a photopolymerizable mixture formed on an insulating substrate according to the resist pattern, and the thick-film paste obtained at this time has almost the same thickness as the photopolymerizable layer on the surface of the insulating substrate and is patterned according to the high-precision pattern defined by the sharp, linear, lateral edge enclosed by the resist image removed by development.
