There is disclosed a rotary compressor (10) which delays a pressure rise on a high pressure chamber side in a cylinder (38,40) of a rotary compression element (32,34) to decrease a high pressure load applied to a roller (46,48) and a rotary shaft (16), thereby improving performance. In the rotary compressor (10) including a sealed container (12) in which an electromotive element (14) a first and a second rotary compression elements (32,34) driven by a rotary shaft (16) of the electromotive element (14) are included, each of the rotary compression elements (32,34) being constituted of a cylinder (38,40), a roller (46,48) fitted into an eccentric portion formed on the rotary shaft (16) to eccentrically rotate in the cylinder (38,40), and a vane (50,52) which abuts on the roller (46,48) to partition the inside of the cylinder (38,40) into a low pressure chamber side and a high pressure chamber side, the inner diameter of a suction passage (58,60) formed in each cylinder is 59% or more and 70% or less of the thickness of the cylinder (38,40).
