Abstract
An outdoor unit of an air-conditioning apparatus includes a bell mouth that has a first tapered portion and a straight pipe portion. The first tapered portion has a linking portion that is continuous with a first bent portion and a second bent portion in a region located between the first and second bent portions and that has an inner surface extending linearly. The angle of inclination of the inner surface of the linking portion relative to a direction along an axis of the straight pipe portion is 33 degrees or more. The ratio of the sum of a first length of the first tapered portion and a second length of the straight pipe portion to the total length of the bell mouth is less than 0.76.
