An elaborately designed structure for containing dust removed from an air filter in an indoor unit reduces user's labor for dust collection as much as possible. A dust collection box has a dust collection container (90) placed so that, in a view from the indoor side (in a plan view), at least a part of the container is positioned outward from an opening (1a) of a ceiling plate (1). A discharge-side duct (74) is connected to the dust collection container (90). Dust removed from the air filter (40) in a casing body (26) is conveyed via the discharge-side duct (74) to the dust collection container (90) by air expelled from an indoor fan (39). |
