PROBLEM TO BE SOLVED: To suppress the wear of a tip seal and improve the durability thereof. SOLUTION: A fixed scroll 4 and a turning scroll 7 are formed out of aluminum alloy, respectively, and anodizing is applied to the fixed scroll 4 and the turning scroll 7 to increase the resistance against wear of an outer surface. Tip seals 13 coming into slide-connect with mating mirror plates 7A, 4A are attached to a tip of a lap part 4B of the fixed scroll 4 and a tip of a lap part 7B of the turning scroll 7, respectively. The tip seal 13 is formed by a resin material containing bronze powders of 15 to 30 wt.%, carbon fibers of 5 to 15 wt.%, molybdenum disulfide of 2 to 10 wt.% and a remaining part made of tetrafluoroethylene resin to increase the resistance against wear of the tip seal 13.
