An air conditioner provided in a ceiling of an air conditioned room, comprising: a face panel including: a panel main body formed by an alternating sequence of four side parts (30a - 30d) and four corner parts (30e - 30h), main outlets (32a - 32d) disposed along each of said side parts, an inlet surrounded by all of said side parts, auxiliary outlets (32e - 32h) disposed in at least one of said four corner parts; a box-shaped casing main body whose lower surface is open, characterized in that, a panel lower surface part is disposed on the lower surface of the panel main body and the panel lower surface part is disposed so that it surrounds the inlet and is surrounded by the auxiliary outlets disposed in at least one of said four corner parts; a drain pan is attached to the lower part of the casing main body, the drain pan including: an inlet hole formed so that it communicates with the inlet, main outlet holes (72a - 72d) formed so that they communicate with the main outlets, and auxiliary outlet holes (72e - 72 g) formed so that they communicate with the auxiliary outlets; and horizontal flaps (35a - 35d) are rotatably supported about longitudinal axes of said main outlets and configured to vary a wind direction of an air current blown out from each of said main outlets, outer circumferential edge parts of the panel lower surface part are disposed so that, in a plan view of the face panel, the outer circumferential edge parts overlap with the portions of the main outlets on the inlet side and the portions of the auxiliary outlets, whereby the outer circumferential edge parts form the edge parts (39a- 39d) of the main outlets on the inlet side and the edge parts (39e - 39h) of the auxiliary outlets on the inlet side, each of said auxiliary outlets is having a circumferential edge part formed so that air is blown out from each of said auxiliary outlets in a fixed direction. a face panel including: a panel main body formed by an alternating sequence of four side parts (30a - 30d) and four corner parts (30e - 30h), main outlets (32a - 32d) disposed along each of said side parts, an inlet surrounded by all of said side parts, auxiliary outlets (32e - 32h) disposed in at least one of said four corner parts;
