In order to reduce noise generated by air sucked in or blown out by a blower, this ceiling-embedded air conditioner comprises: a heat exchanger (7); a blower (6) that is arranged on the inside with respect to the heat exchanger (7), and that has a tubular shroud (25) the diameter of which increases toward the outside; a bell mouth (12) arranged below the shroud (25) and on the suction side of the blower (6); and a drain pan (10), in which is formed a recessed drain groove (18) in which a lower portion of the heat exchanger (7) is accommodated. The ratio of a second gap B between the discharge-side end of the shroud (25) and an inner-peripheral wall part (18a) on the inside of the drain groove 18 relative to the heat exchanger (7) to a first gap A between the upper end of the bell mouth (12) and the suction-side end of the shroud (25) is B/A ≤ 3 or 10 ≤ B/A.
