PROBLEM TO BE SOLVED: To increase the reliability of a fixed scroll and a rotary scroll of a scroll compressor to match the compressor to recent refrigerating air conditioners increased in efficiency and life and using a high-pressure refrigerant such as carbon dioxide. SOLUTION: The thickness H of an end plate of the rotary scroll 13 on the inside of a bearing housing part 13c is 10-35% of the inner diameter D of the bearing housing part 13c. When the scroll compressor is under high load, the tooth bottom of the end plate 13a of the rotary scroll 13 corresponding to the bearing housing part 13c and the winding start part at the lap end 12b of the fixed scroll 12 are deformed, and also the winding start part of the fixed scroll 12 is heated, and thermally expanded to the rotary scroll 13 side. However, since the tooth bottom of the end plate 13a of the rotary scroll 13 on the inside of the bearing housing 13c is flexibly deformed to the end 12b of the fixed scroll 12 by pressure, nonuniform contact does not occur, and the high reliability of the scroll compressor can be realized.
