Abstract
A scroll compressor includes fixed and orbiting scrolls, and satisfies at least one of a first condition and a second condition. In the first condition, a first gap between a distal end of the first wrap and the second base changes heading from an outer peripheral side of the first wrap to an inner peripheral side. In the second condition, a second gap between a distal end of the second wrap and the first base changes heading from an outer peripheral side of the second wrap to an inner peripheral side. A rate of change in the first gap in one area is greater than a rate of change in the first gap in another area. A rate of change in the second gap in one area is greater than a rate of change in the second gap in another area.
