An axial compressor includes: a rotary shaft rotatably supported in a cylindrical casing such that an annular fluid passage is defined therebetween; a rotor blade row including rotor blades provided on an outer circumferential surface of the rotary shaft; a stator blade row including stator blades provided on an inner circumferential surface of the casing at a position adjacent to and behind the rotor blade row; and a recirculation passage provided in the casing and having a suction port and an ejection port on downstream and upstream sides of the fluid passage, respectively. The suction port is located rearward of leading edges of bases of the stator blades, and the ejection port is located at a position forward of centers of tips of the rotor blades and at least partially opposing the tips of the rotor blades.
