PROBLEM TO BE SOLVED: To provide a method for working a vane for a rotary compressor, capable of preventing excessive initial wear of a vane and a rolling piston by improving surface roughness and circularity of a vane tip part, making roughness and circularity of the vane tip part in a direction sliding on the rolling piston and in a direction other than the sliding direction equal and securing constant roughness and circularity in any directions, and a rotary compressor including the vane grounded by the same method. SOLUTION: In the rotary compressor in which the rolling piston eccentrically rotates in a cylinder with sliding on the vane 2 to compress refrigerant, grid shape grind finish in crossing two directions are applied on a section where the vane 2 and the rolling piston slides.
