Abstract
A band-pass filter includes a main body formed of a dielectric, a plurality of resonators, a shield, and a partition formed of a conductor. Each of the plurality of resonators includes a resonator conductor portion. The resonator conductor portion has a first end and a second end opposite to each other in the longitudinal direction. The first end is connected to a ground, and the second end is open. The partition extends to pass through between the respective resonator conductor portions of two resonators, and is electrically connected to the shield.
