摘要： A stripline filter includes a ground electrode, input and output electrodes, top-surface resonant lines, side-surface resonant lines, side-surface line portions, connection electrode portions, and top-surface line portions. The ground electrode is provided on the bottom side of a dielectric substrate. The input and output electrodes are provided on the bottom surface of the substrate so as to be separate from the ground electrode. The top-surface resonant lines are provided on the top surface of the substrate. The side-surface line portions, the connection electrode portions, and the top-surface line portions connect two of the top-surface resonant lines to the input and output electrodes. The line width of the two top-surface resonant lines is smaller than the line width of the remainder of the top-surface resonant lines.
