PROBLEM TO BE SOLVED: To inhibit the attenuation of balanced signals output from output terminals 17 and 18 to an unbalanced signal input from an input terminal 15. SOLUTION: In a balun 14, a first unbalanced side line 23 and a second balanced side line 24 are arranged on approximately the same plane. In the balun 14, the first unbalanced side line 21 is disposed at a specified distance from the first balanced side line 23 in the upper section of the first balanced side line 23, and a second unbalanced side line 22 is disposed at the specified distance from the second balanced side line 24 in the lower section of the second balanced side line 24. According to the constitution, a distance is increased between the first unbalanced side line 21 and the second one 22, and the mutual large cancellation of a current flowing through the first unbalanced side line 21 and the current flowing through the second one 22 can be inhibited.
