PROBLEM TO BE SOLVED: To facilitate designing, when a >=3-input, 1-output switch, a 1-input, >=3-output switch, etc., are generated. SOLUTION: This transmission line switch 11 has input terminals 15a to 15c for inputting input signals and is equipped with (n) high-frequency amplifiers 12a to 12c which turn on and off by changing bias conditions, (n) transmission lines 13a to 13c which are equal in length to one another and connect output points 16a to 16c of the (n) high-frequency amplifiers 12a to 12c, (n-1) connection points 33a and 33b, and an output terminal 34, and (n-1) 2nd transmission lines 14a and 14b, which have lengths equal to integral multiples of a half of the in-line wavelength and connect two adjacent points among the (n-1) connection points 33a and 33b and output terminal 34.
