ABSTRACT:
A filter employing Triplate type microstripline as the base element comprises first and second dielectric substrates which are superposed with each other so as to hold a resin sheet therebetween, and are contained in a metal case. The respective dielectric substrates are provided on outer major surfaces with ground electrodes to be electrically connected with the metal case. Resonance electrodes are provided on inner major surfaces of the respective dielectric substrates to be electrically connected with relating ground electrodes through end surfaces of the dielectric substrates. The resin sheet holds metal pins passing through the same along the direction of thickness thereof, so that the respective resonance electrodes of the first and second dielectric substrates are electrically connected with each other by the metal pins.
