Abstract: An impeller according to the present disclosure includes a hub and wings. Each of the wings has a leading edge portion and a body portion. The leading edge portion is positioned on an upper surface side of the hub. The body portion is positioned on a lower surface side of the hub. A tip of the leading edge portion and a tip of the body portion extend from the upper surface side of the hub toward the lower surface side of the hub on a side opposite to a side where the wing is in contact with the hub. In a plan view of the wing seen from a radial direction perpendicular to an axis of the impeller, a profile of the tip of the leading edge portion has a linear shape and a profile of the tip of the body portion has a curved shape.
