Abstract
A strip line filter includes a substantially rectangular plate-like shaped dielectric substrate. A ground electrode is arranged on a bottom surface of the substrate. A first resonant line and a second resonant line face the ground electrode through the substrate. Input/output electrodes are connected to the corresponding resonant lines. The first resonant line includes a first top-surface line, a connection line, and a second top-surface line. The first top-surface line is arranged on the top surface of the substrate and extends so as to pass a portion adjacent to a portion, on the left side, of a third top-surface line. The connection line and the second top-surface line are branched from the first top-surface line and pass a portion adjacent to a portion, on the right side, of the third top-surface line.
