Abstract The present invention provides a voltage nonlinear resistor unit and a lightning arrester unit which can be made small in size, without causing reduction in the rated discharge withstand current. To solve the problem, a voltage nonlinear resistor is made by molding and sintering raw material into a cylindrical sintered compact, providing a prescribed surface roughness to both end surface of the said compact. Next ,one or a plurality of voltage nonlinear resistors are laminated to the compact, and terminal metal fittings are attached to both ends of the compact. Soldering material is provided to the location between the voltage nonlinear resistors and between the resistors and terminal fittings to bond therebetween.
