    • PROBLEM TO BE SOLVED: To provide an efficient and low-cost fan by reducing a blowing loss in an inner air passage of the fan, to provide an electric blower with the fan, and to provide a vacuum cleaner using the electric blower. SOLUTION: This fan includes: a doughnut-shaped front plate 10 having an intake port 9 for sucking air at a central part thereof; a disc-like rear plate 11 facing the surface of the front plate 10; and blades 12 partitioning a space between the front plate 10 and the rear plate 11 with a predetermined interval in the circumferential direction to form an inner air passage extending in the radial direction. This fan discharges air sucked by rotation of the blades 12 from the intake port 9 discharges from an outer diameter side of the inner air passage by making the air flow from an inner diameter side to the outer diameter side of the inner air passage. The blade 12 is formed of a thin piece obtained by scraping the surface of the rear plate 11, and the thin piece is raised in the surface of the rear plate 11 to have a standing part 12a, and the inner air passage is formed by the standing part of the rear plate 11 and the front plate 10, surrounding the same.
