The present invention provides a generator that can draw in wind regardless of the direction in which the wind is blowing, and can efficiently generate power by utilizing the wind that was drawn in. This generator is equipped with: a stator part 100 that is formed by attaching first coils to at least one of an inner circumferential side and an outer circumferential side of a ring member fixed to an installation surface; and a rotor part 200 that is formed by attaching magnet coils, which generate a magnetic field as a result of electrical conduction thereto, to a ring member concentric with the stator part 100 such that the magnet coils face the first coils with a prescribed gap therebetween. The rotor part 200 has a plurality of blade parts 240 that are rotatably supported on a column part 110 provided to the center of the stator part 100, and that are formed so as to protrude radially outward from an outer circumferential side surface. The blade parts 240 rotate as a result of receiving the wind discharged from a discharge port 11d.
