In a scroll compressor, a thrust ring is mounted between a movable-side flat plate part of a movable scroll and a housing. An upper surface of the thrust ring slides relative to a lower surface of the movable-side flat plate part and supports a thrust load from the movable scroll. A resinous coating is formed on the upper surface of the thrust ring which slides relative to the movable-side flat plate part. The resinous coating is composed primarily of fluorocarbon resin and polyamide-imide resin. The component percentage of the polyamide-imide resin in the primary component of the resinous coating is set, such that it is not less than 65% by mass nor more than 85% by mass.
