A rotary compressor includes: a cylinder main body (11) that forms a cylinder chamber (10); a rotor (14) fitted onto an eccentric part (9a) of a rotating shaft (9), orbits in the cylinder chamber (10) in accordance with rotation of the rotating shaft, and whose outer circumferential surface (14a) is brought into sliding contact with an inner circumferential surface; and a blade (17) whose front end portion (17a) is brought into contact with the outer circumferential surface (14a) of the rotor and that slides in a blade groove (15) provided in the cylinder main body in accordance with orbiting of the rotor. The blade (17) has a hollow portion (171) therein that allows the blade to be bent in a thickness direction thereof, and the hollow portion is open to a rear end portion (17b) and both side portions of the blade.
