<P>PROBLEM TO BE SOLVED: To reduce a flow passage resistance of an inner wall of a lead-out pipe of an accumulator mounted on an air-conditioning compressor so as to improve the efficiency of the compressor, in consideration of a problem of a conventional accumulator such that a loss is caused by the flow passage resistance between an inner wall of a lead-out pipe and refrigerant gas because the refrigerant gas flowing from an introduction pipe is let out through the lead-out pipe having a small diameter so that an input of a compressor is increased. Ž<P>SOLUTION: In order to reduce the flow passage resistance of the inner wall of the lead-out pipe of the accumulator so as to improve the efficiency of the compressor, a number of minute dimples are formed on the inner wall of the lead-out pipe of the accumulator.
