PROBLEM TO BE SOLVED: To realize a high frequency switch having many outputs which has less loss and has less signal leakage to other routes. SOLUTION: In this high frequency switch, a plurality of tristate switches 1a to 1e are include and are connected like a tournament by strip lines 3, and lengths S1 to S5 of strip lines 3 from branch points N1 to N3 to switches 1a to 1e ate so adjusted that real parts of impedance obtained by viewing turned-off switches 1a to 1e from branch points N1 to N3 of lines 3 connected to switches 1a to 1e may be maximum and imaginary parts of this impedance may be 0. Lengths L1 to L3 of strip lines 3 from branch points N3 and N4 of roots of lines 3 connected to branch points N1 to N3 to these branch points N1 to N3 are adjusted to integral multiples of the half-wave length.
