A rotary compressor 1 includes a pair of closing members 11 and 12 that close axial front and rear opening portions of a cylinder 5, and a rotor 6 that is accommodated within the cylinder 5 and rotated by a motor. Concave portions 11C and 12C having the same depth are respectively formed in inner wall surfaces 11A and 12A of the closing members 11 and 12, and the concave portions 11C and 12C are filled with synthetic resin coatings 22. Accordingly, the surfaces of the synthetic resin coatings 22 are flush with the inner wall surfaces 11A and 12A located outwardly adjacent thereto (a left side in the drawing). The rotary compressor 1 which can prevent a seizure on end surfaces 6A and 6B of the rotor 6, and can be manufactured at low cost can be thereby provided.
