A multilayer filter is provided to suppress deterioration of a high frequency characteristic by including Li in a diffusion layer of an inductor layer to suppress increase of permittivity of the diffusion layer. A multilayer filter(1) includes a laminate(2). The laminate includes an inductor unit and a varistor unit. The inductor unit has an inductor conductor unit formed in an inductor layer. The varistor unit has a varistor conductor unit in a varistor layer. The varistor layer contains ZnO as a main component and at least one element selected from a group consisting of Pr and Bi, Co, and Al as additives. The inductor layer contains ZnO as a main component and substantially does not contain Co and Al. A diffusion layer is formed on an interface in the inductor layer and contains Li. The inductor conductor unit is spaced apart from the interface by more than 20 um. The varistor conductor unit is spaced apart from the interface by more than 40 um.
