Abstract
A resistor is provided that is made by laminating at least two resistive layers, where these resistors have conductive particles held in a binder resin. The resistors are laminated such that a top resistor covers a bottom resistor, and a surface of the top resistor is exposed. The resistivity of the top resistor is made smaller than that of the bottom resistor. The top resistor contains carbon fiber and carbon black, where the central particle size of the carbon fiber ranges from 3.5 to 9.0 &mgr;m. The resistor has excellent durability and micro-linearity characteristics. The resistor may also be used as a variable resistor.
