PROBLEM TO BE SOLVED: To provide a branching filter capable of widening the band width. SOLUTION: The branching filter consists of a first capacitor with its one end coupled to an input terminal; a first inductor and a second capacitor which are coupled in series with the other end of the first capacitor; a third capacitor in which its one end is coupled with the other end of the first capacitor; a fourth capacitor in which its one end is coupled with the other end of the first capacitor; a second inductor and a fifth capacitor which are coupled in series between one end and the other end of the fourth capacitor; a sixth capacitor which is coupled to the other end of the fourth capacitor; a first output terminal which is coupled to the other end of the fourth capacitor; and ground terminals which are coupled to the other ends of the first inductor and the second capacitor coupled to each other, in series with the other end of the third capacitor, and to the other end of the sixth capacitor, respectively.
