Abstract
A metal oxide resistor for suppressing variations in resistivity in use in an atmosphere at a high temperature or humidity. Such a metal oxide resistor includes a sintered body in which carbon particles having an average grain size of 1 .mu.m or less exist in the grain boundaries of metal oxide particles in an amount of 0.05 to 3 wt %, and electrodes formed on at least two opposing surfaces of the sintered body.
