Abstract
To provide a millimeter waveband filter which can vary a resonance frequency in a wider band without causing deterioration of resonance characteristics due to leakage of electromagnetic waves. In a millimeter waveband filter, a first waveguidesand a second waveguideare relatively moved to vary the interval between the electric wave half mirrorsA andB, and the resonance frequency of a resonator formed between the mirrors varies to selectively transmit resonance frequency components. A groovewhich has a length p along a longitudinal direction of the transmission line corresponding to a ¼ wavelength of electromagnetic waves to be a leakage prevention target is provided on the outside of the second waveguidefacing the inside of the first waveguide, thereby preventing leakage of electromagnetic waves from the gap between the first waveguideand the second waveguide
