PROBLEM TO BE SOLVED: To improve durability by compatibly establishing cooling of oil and avoidance of metal contact of a fixed scroll and a turning scroll while reducing leak loss and improving efficiency of a compressor by providing an oil supply hole and a lap upper surface groove and reducing leak gap of a center part by oil film in a scroll compressor for natural refrigerant R744 generating high differential pressure in a compression chamber. SOLUTION: The scroll compressor securing high efficiency and durability can be constructed by providing a path 18 supplying oil to the lap upper surface 19 of the turning scroll 4 in the scroll compressor and securing quantity of oil supplied into the compression chamber by moreover providing an oil supply path on the lap upper surface 19 and a lap side surface 20.
