摘要：A dielectric filter includes a laminate substrate formed by laminating andbonding a plurality of dielectric sheets, belt-like resonance electrodes formed onpredetermined bond surfaces of the dielectric sheets, input/output electrodes formed atpredetermined positions of an outer periphery of the laminate substrate and connectedto the belt-like resonance electrodes, and earth electrodes formed on the outerperiphery of the laminate substrate under a non-connection state with the input/outputelectrodes. The end portions of the belt- like resonance electrodes extend to both sidesurfaces of the laminate substrate. One end of each belt-like resonance electrode isconnected to the earth electrode formed on one of the side surfaces of the laminatesubstrate and serves as a short-circuit terminal, and the other end of the belt- likeelectrode is exposed on an ungrounded portion on the opposite side surface and servesas an open terminal.
