This stationary vane ring comprises a vane group having a plurality of vanes arrayed in the circumferential direction of an axis, a shroud segment in which the radial ends of the plurality of vanes of the vane group are connected to form an arc so as to connect the plurality of vanes in the circumferential direction, and a pressing portion that applies radial pressure to the vane group so that the vane group is pressed against the shroud segment, the pressing portion having pressure distribution such that the pressure at the circumferential center of the shroud segment is less than the pressure at both circumferential ends of the shroud segment.
