Abstract

An object of the present disclosure is to provide a common mode noise filter that can be used in a high-frequency band. The common mode noise filter of the present disclosure includes first to fifth insulator layers and stacked body in which first to fifth insulator layers are stacked along a vertical direction. The common mode noise filter further includes first spiral conductor and second spiral conductor that are formed inside stacked body and face each other across first insulator layer. The common mode noise filter further includes first pad connected to an inner end of first spiral conductor and second pad connected to an inner end of second spiral conductor. Neither first pad nor second pad overlaps each of first spiral conductor and second spiral conductor in top view.
