PROBLEM TO BE SOLVED: To improve a cooling effect by cooling fin in a scroll fluid machine. SOLUTION: In this scroll fluid machine, a closed chamber of which fluid volume changes with turning of a turning lap 9 is formed by engaging a spiral fixed lap 5 disposed on the front surface of a fixed scroll 1 with a turning lap 9 that is journaled to an eccentric shaft part 14 of a spindle 13 and disposed on the front surface of a turning scroll 7 having a built-in rotation preventing mechanism 17. The turning scroll 7 is integrated with a bearing plate 11 that is pivotally supported on the eccentric shaft part 14 of the spindle 13 and has the built-in rotation preventing mechanism 17, a plurality of cooling fins 10 are provided projectedly on the back surface of the turning scroll, and a plurality of cooling fins 12 to which cooling gas applying the cooling fins 10 in the turning scroll 7 is applied are provided projectedly on a surface facing to the turning scroll side of the bearing palate 11.
