Abstract: A ceiling-embedded air conditioner includes: a ceiling-embedded casing body; a turbo fan disposed inside the casing body; a heat exchanger disposed inside the casing body on an outer peripheral side of the turbo fan; and an electrical equipment box disposed along a part of the heat exchanger at the upstream side of a ventilation direction. The casing body has a square shape with first to fourth side plates. The heat exchanger has first to fourth heat exchange portions bent along the first to fourth side plates respectively. An end portion of the first heat exchange portion and an end portion of the fourth heat exchange portion are disposed at a corner for tube connection out of the four corners of the casing body. The electrical equipment box is disposed to extend from the corner for tube connection toward the first heat exchange portion and the fourth heat exchange portion.
