PROBLEM TO BE SOLVED: To provide a high output branching distribution amplifier at a low cost. SOLUTION: At least three amplifier circuits 6, 7a-7b, 8a-8h are connected in a plurality of stages via branch distribution circuits 9, 10a-10b. An input terminal 11 is connected to an input side of the amplifier circuit 6 belonging to a 1st amplifier stage A1. Output terminals 12a-12h are connected respectively to output sides of the amplifier circuits 8a-8h belonging to a final amplifier stage A3.
