A rotary valve (2) includes: a housing (10) including a valve accommodation unit (11); a rotor (12) being housed rotatably about an axis (X) in the valve accommodation unit (11); and a sealing object (S) being disposed between an inner wall surface of the valve accommodation unit (11) and an outer wall surface of the rotor (12). A plurality of first flow path openings (11a) are formed in the inner wall surface and a plurality of second flow path openings (12c) that can communicate with the first flow path openings (11a) are formed in the outer wall surface (12s). In the sealing object (S), a first seal (21) is overlaid on a second seal (22), the first seal (21) including first seal openings (21a) that communicate with a plurality of the first flow path openings (11a) and being in contact with the inner wall surface, the second seal (22) including second seal openings that overlap with a plurality of the first seal openings (21a) and being in contact with the outer wall surface of the rotor (12), and the second seal (22) is divided into a plurality of pieces in a circumferential direction about the axis (X) and each of the pieces is supported unmovably with respect to the inner wall surface.
