Abstract
A balun includes an unbalanced terminal; first and second balanced terminals; first and second main lines; first and second sub-lines; and a parallel line. The first main line has an end connected to the unbalanced terminal. The second main line has an end connected to another end of the first and second end that is open. The first sub-line is connected between the first and a reference potential, and is coupled to the first main line. The second sub-line is connected between the second balanced terminal and the reference potential, and is coupled to the second main line. The parallel line is connected in parallel with a part of the first sub-line. The line length of a specific portion of the first sub-line that is connected in parallel with the parallel line is different from the line length of the parallel line.
