A cavity filter having a ceramic resonator is disclosed. The disclosed cavity filter may include: a housing in which at least one cavity is formed and which has a ceramic resonator held in the cavity; a ceramic ring joined to an upper part of the ceramic resonator; and a cover joined to one side of the housing, where a through-hole is formed in the ceramic resonator to form a penetration from one side to the other side along one direction, and a metal layer is formed on a surface on the one side of the ceramic resonator, on a surface on the other side of the ceramic resonator, and on the inner perimeter of the through-hole. The disclosed cavity filter can provide the advantage that it can be manufactured as a compact structure.
