Abstract:
1. A multilayer filter comprising: a laminate having a first multilayer portion comprising a stack of insulator layers, and a second multilayer portion comprising a stack of varistor layers; a first terminal electrode, a second terminal electrode, and a third terminal electrode formed on the laminate; an inductor part which is constructed so that a plurality of conductor portions formed in the first multilayer portion are electrically connected to each other, one end of which is electrically connected to the first terminal electrode, and an other end of which is electrically connected to the second terminal electrode; and a varistor part which is constructed so that a first varistor electrode electrically connected to the first terminal electrode or to the second terminal electrode, and a second varistor electrode electrically connected to the third terminal electrode are formed in the second multilayer portion with the varistor layer in between, wherein the inductor part has a DC resistance of 4 Ω-100 Ω.
