Abstract: The present invention aims at providing a rotary joint which is of a thin type and has broad band characteristics and which is low in loss and is excellent in power resistance as well. In order to attain the object, the rotary joint includes: first and second polarizers each having a common side terminal connected to a waveguide portion, and two branch side terminals through which two polarized waves orthogonal to each other inputted through the common side terminal are separately taken out; and the waveguide portion which has a rotatable connection portion, one end of which is connected to the common side terminal of the first polarizer and the other end of which is connected to the common side terminal of the second polarizer.
