Patent ID: 8222975

Claim:
A transmission line type resonator formed of a laminate body constituted by a plurality of dielectric sheets, comprising: a transmission line of complex right hand left hand system provided between the plurality of dielectric sheets; and an external connection terminal provided at an end face of the transmission line type resonator, the connection terminal being connected with the transmission line of complex right hand left hand system, wherein the transmission line of complex right hand left hand system is structured of a line electrode disposed on one of the dielectric sheets, a connection pattern electrode whose line width is smaller than that of the line electrode, connected with the line electrode and formed on a same surface extending from an edge of the line electrode in a same layer in which the line electrode is formed, a grounding electrode connected with the connection pattern electrode, and an input/output pattern electrode disposed so as to make capacitive coupling with the line electrode, connected with the external connection terminal.
