PROBLEM TO BE SOLVED: To suppress the influence by a branch transmission line in which a switch is opened, in a high-frequency power compositor or distributor called as a power switchable combiner/divider which is preferably embodied to a radio relay device of a high-frequency signal such as a terrestrial digital television broadcast or a cellular phone, connects one end of a single transmission path to one end of a branch transmission path, and is provided with a switch for opening/closing the high-frequency signal on each branch transmission path. SOLUTION: Corners of branch switches SW1-SW3 provided on branch transmission paths K1-K3 are chamfered, and these are closely disposed. Accordingly, the branch switches SW1-SW3 can be closely disposed by the connection point 60 of the transmission paths K0; K1-K3, and the adverse effect due to open state of the portions between the branch switches SW1-SW3 and the connection point 60 of the branch switches K1-K3 can be stopped to the minimum.
