Abstract:
This cavity resonator is configured so as to form a choke structure in which the opening (9a) of a space (9) is electrically open and the hole end (5a) of a through-hole (5) on a recess bottom surface (4a) side is electrically short-circuited at the frequency of an electromagnetic wave propagating through a cavity portion (1a), in a state where the space (9) is formed by a recess (4), a screw (7), and a nut (8) since there is a gap between an opposing surface (8d) and the recess bottom surface (4a).
