Beschreibung
Zusammenfassung:	A high frequency filter includes: a multilayer substrate including a first substrate for which lands are provided, a second substrate for which lands are provided, and a third substrate for which lands are provided, the third substrate being sandwiched between the first substrate and the second substrate; a columnar conductor electrically connected to the lands in the multilayer substrate; and columnar conductors provided to surround the columnar conductor, electrically connected to a ground plane of the first substrate, and electrically connected to a ground plane of the second substrate. The spacing between the lands of the first substrate and the lands of the third substrate and the spacing between the lands of the second substrate and the lands of the third substrate are electrical lengths of 90 degrees or less at the cutoff frequency.
