ABSTRACT:
The element size of a stripline filter that achieves a high efficiency percentage with optional stable filter characteristics, is reduced. A stripline filter includes substantially L-shaped top surface resonant lines. The top surface resonant lines include connection electrode parts, first line parts, and second line parts. The connection electrode parts are formed so as to have a width greater than line widths of side surface resonant lines. Each line part faces an edge of a corner portion of a central top surface resonant line at an interval. An edge of each first line part on an edge side of a dielectric substrate, other than a connection portion with the connection electrode part, faces an edge of the dielectric substrate at an interval.
