Abstract
(EN)
Provided is a band-pass filter which allows the bandwidth of a pass band to be easily changed. This band-pass filter (1B) is provided with: a housing (11); a plurality of resonant plates (12) housed in the housing (11); a first coupling conductor (15) connecting adjacent two of the resonant plates (12); and a second coupling conductor (16) disposed at a position acting on a coupling coefficient between the adjacent two of the resonant plates (12), wherein a distance between the resonant plate (12) and the second coupling conductor (16) is changeable.
