Abstract
A centrifugal multiblade blower includes: an electric motor; and an impeller blowing off air outward in a radial direction by being rotated by the electric motor. A main plate of the impeller has an uneven part on one surface adjacent to the electric motor in a thickness direction of the main plate. The one surface is in contact with air passing through inside of the electric motor. A surface shape of the uneven part is formed in manner that, among a whole surface of the uneven part, a total surface area of a surface facing inward in a radial direction of the motor is larger than an imaginary smooth surface on which the surface shape of the uneven part is defined to be a smooth surface without the uneven part.
