Abstract:
1. A stripline filter that is to be mounted on a set substrate by means of soldering, the stripline filter comprising: a dielectric substrate having opposed first and second surfaces, and side surfaces connecting the first and second surfaces; a grounding electrode on the second surface of the dielectric substrate; a plurality of principal-surface lines on the first surface of the dielectric substrate, the plurality of principal-surface lines opposing the grounding electrode with the dielectric substrate therebetween so as to form one or more resonators; an input/output electrode on the second surface of the dielectric substrate, the input/output electrode being coupled to any of the one or more resonators; a plurality of side-surface lines on the side surfaces of the dielectric substrate, the plurality of side-surface lines configured to be wetted by solder when soldered; and a common electrode on the dielectric substrate, the common electrode connected to a single principal-surface line of the plurality of principal-surface lines and connected to the grounding electrode via at least one of the plurality of side-surface lines, the plurality of side-surface lines being provided in a greater number than the plurality of principal-surface lines.
