PROBLEM TO BE SOLVED: To provide a multiple branch distribution phase shifter whose arrangement is simple, area is small, and cost can be reduced. SOLUTION: A multiple branch distribution phase shifter is formed on a dielectric board, and has the first or n(n≥2)-th output side strip conductor which, when the first or n-th ring arranged in a concentric fashion with an arbitrary point as a center is supposed, has an arc form composing a part of the first or n-th ring respectively and whose both ends are made output ends. The shifter is formed on the dielectric board, and has an input side strip conductor whose one end is determined in a center of the ring. The shifter has the first or n-th sliding portion having an arc form composing a part of the first or n-th ring respectively and whose length is shorter than the output side strip conductor, and an arm portion which has the first or n-th sliding portion and which can rotate around the center of the ring. An insulating body exists between the first or n-th output strip conductor and the first or n-th arc like sliding portion, and between the input side strip conductor and the arm portion.
