The stationary scroll member has a high-pressure central port located in the vicinity of the center thereof and having a profile which is defined by a boundary line located in a region defined by first and second circles both being centered at a point located on a straight line extending through the positions in which the inner ends of wraps are contact with the inner side walls of the opposing wraps, respectively, in the reference condition. The first circle has a diameter equal to the distance between the above-mentioned positions and the second circle has a diameter such that it is in contact with the inner side walls of the wraps.
