Abstract

In a multi-functional multilayer device including a body (10) having a varistor section (2) and a capacitor section (3) stacked and integrated therewith, the adhesion between a varistor layer and a dielectric layer is improved when the varistor layer (22) contains zinc oxide as a main component and at least one lanthanide oxide as an auxiliary component, and the dielectric layer (32) contains titanium oxide or lanthanum/titanium oxide as a main component. The device experiences little warpage upon firing when glass is added to the dielectric layer. A high resistivity intermediate layer (5) disposed between the varistor and capacitor sections (2 and 3) prevents the deterioration or loss of varistor and capacitor properties by interdiffusion of elements between the varistor and capacitor sections.
