The present invention relates to a scroll fluid machine, wherein, a gap between opposing wrap portions is narrowed to increase compression efficiency, and an amount of machining time is reduced to thereby increase productivity. A plurality of proximate portions 8 are formed, at spacings in a spiral direction, on an outer peripheral surface 3 B of a wrap portion 3 of a fixed scroll 1. Flat surfaces 8 A are used to connect adjacent proximate portions 8. Similarly, a plurality of proximate portions 14 are formed, at spacings in the spiral direction, on an outer peripheral surface 13 B of a wrap portion 13 of an orbiting scroll 11. Flat surfaces 14 A are used to connect adjacent proximate portions 14. In this way, the outer peripheral surfaces 3 B and 13 B of the wrap portions 3 and 13 can be formed in polyangular shapes, so as to reduce a gap between the wrap portions 3 and 13 and simplify the shapes. As a result, an amount of machining time can be reduced.
