PROBLEM TO BE SOLVED: To provide a tip seal part structure of a scroll compressor, without generating an excessive load on the tip of a scroll wall, that is, capable of improving efficiency in the compressor, while securing sealability equal to a conventional structure. SOLUTION: This scroll compressor is constituted so that a fixed scroll and a movable scroll are mutually meshed, and a groove extending along a spiral shape of a spiral body is formed on a tip surface of the spiral body of at least one scroll, and a tip seal is arranged in the groove so as to be capable keeping in slidable contact with a bottom plate surface of the other scroll opposed to the tip surface, for projecting from the tip surface. The scroll compressor is characterized in that the tip seal has a large projection part having a larger projection margin from the tip surface and a small projection part having a smaller projection margin from the tip surface, and the large projection part and the small projection part are alternately arranged in the direction along the spiral shape of the spiral body.
