Abstract

PURPOSE:To prevent the effect of a Schottky barrier, and to obtain low varister voltage and improve voltage non-linearity by forming internal electrodes injected at the low melting point to porous layers in the laminate of a semiconductor ceramics sintered body as a varister, to a grain boundary layer of which a resistance layer is shaped and which has capacitive, and the porous layers. CONSTITUTION:Semiconductor ceramics 4 are prepared by baking tabular green sheets 1a-1f mainly comprising strontium titanate. Internal electrodes 7... and external electrodes 8, 8 are manufactured by pressure-injecting and forming the single body or alloy of a base metal having the low melting point to porous layers mentioned below and external porous bodies. When a base metallic solution is injected to the porous layers 3 and the porous bodies 5, the internal electrodes 7 and the external electrodes 8 are shaped. Capacitance is increased in response to no formation of a Schottky barrier, varister voltage is lowered, and a voltage non-linear coefficient is improved.
