发明名称 Multilayer filter
摘要 An object of the present invention is to provide a multilayer filter constructed so as to be less likely to suffer peeling between a varistor part and an inductor part. A multilayer filter 10 as a preferred embodiment has a structure in which a varistor part 20 and an inductor part are stacked. The varistor part 30 consists of a stack of varistor layers 31, 32 with internal electrodes 31 a, 32 a, and the varistor layers contain ZnO as a principal component, and contain at least one element selected from the group consisting of Pr and Bi, Co, and Al as additives. The inductor part 20 consists of a stack of inductor layers 21 - 24 with conductor patterns 21 a- 24 a, and the inductor layers contain ZnO as a principal component and substantially contain neither Co nor Al.
