PROBLEM TO BE SOLVED: To reduce fluid loss when fluid flows from/to a compression chamber on a turning inner line side to/from a compression chamber on a turning outer line side and thereby to improve compression efficiency, while implementing size reduction and high pressure ratio. SOLUTION: A scroll compressor comprises: a fixed scroll 7 having a scroll- shaped lap portion 7b; a turning scroll 8 having a scroll-shaped lap portion 8b; discharge valves disposed to discharge portions of the compression chambers. The pair of the compression chambers 13a and 13b respectively on the turning inner line side and on the turning outer line side is formed between the lap portions 7b, 8b. The turning scroll 8 is meshed with the fixed scroll 7 to be capable of turning so that the size of compression chambers is reduced and the compression chamber 13a communicates to the compression chamber 13b, a winding end side of the lap portion 8b is elongated to a winding end side of the lap portion 8b to be in an asymmetry lap shape. The compression chamber 13a communicates to the compression chamber 13b such that a portion where a capacity reduction amount of the compression chamber 13a on the turning inner line side is larger than that of the compression chamber 13b on the turning outer line side is provided.
