To stably hold a tip seal without requiring a difficult processing when providing the tip seal also on a step part of a wrap of a 3D-type scroll compressor. In a scroll compressor 1, a tip seal 40, which is interposed between a wrap 21 and an end plate 300 of the mating scroll, is configured of an outer peripheral tip seal 41 provided on the outer peripheral side of a step part 21C, a step tip seal 42 provided on the step part 21C, and an inner peripheral tip seal 43 provided on the inner peripheral side of the step part 21C. The step tip seal 42 is provided continuously on a leading end part T of an outer peripheral-side wrap 21B, a side surface part S of the step part 21C opposite to a stepped wall 30C, and a leading end part T of an inner peripheral-side wrap 21A. A border Bd between the step tip seal 42 and the inner peripheral tip seal 43 always lies on the outside of a circular path R which the step part 21C traces as the scroll orbits. |
