<p>PURPOSE:To provide a composite varistor in which a varistor voltage without reducing a nonlinear coefficient to enhance a noise absorption characteristic and also a frequency characteristic can be enhanced by avoiding a decrease in electrostatic capacitance when a varistor element is miniaturized. CONSTITUTION:A ceramic sintered body 2 having a voltage nonlinear characteristic contains Co having 0.01 to 0.10mol% when converted into CoO, and borosilicate zinc is diffused in the sintered body 2 by 0.1 to 1.5wt% to construct a composite varistor 1.</p> |
