Abstract
An objective is to provide a multilayer filter capable of preventing an electric current rapidly flowing by virtue of varistor effect, from passing as noise, upon application of noise of a high voltage over a varistor voltage to its input. A multilayer filter has an inductor partand a varistor partin a laminate, and the inductor parthas the DC resistance of 4 Ω-100 Ω. This prevents an electric current rapidly flowing by virtue of the varistor effect, from passing as noise, upon application of noise of a high voltage over the varistor voltage to the input.
