PROBLEM TO BE SOLVED: To provide a brunched-line polarized wave separator capable of securely performing polarized wave separation, and capable of being manufactured by a simple manufacturing method. SOLUTION: In a brunched-line polarized wave separator, a groove 5 for constituting a branched waveguide is formed so that at least a part among linear polarized wave components which are polarized into a Z direction is made to be passed therethrough from among electromagnetic waves to be inputted into an input port. In a groove for constituting a main waveguide, a narrowing portion 7a including a portion having a predetermined depth by making depth of the groove shallower than the other portion of the groove is to be provided at more output port side than a connection surface relating to at least one branched waveguide among connection surfaces for branching each branched waveguide from the main waveguide.
