Abstract

A filter element includes a laminate including insulator layers. A ring conductor pattern is provided on one of the insulator layers. Linear conductor patterns of a first inductor having a helical shape with an axial direction thereof being a laminating direction of the laminate and linear conductor patterns of a second inductor having a helical shape with an axial direction thereof being the laminating direction are provided on predetermined ones of the insulator layers. The ring conductor pattern is arranged such that inner regions of the linear conductor patterns of the first inductor and inner regions of the linear conductor patterns of the second inductor are included in an inner region of the ring conductor pattern.
