An air conditioner comprises an air intake port (4) for introducing the air in a room into the casing of an indoor machine (1), an air discharge port (5) formed at the lower part of the casing, an air flow path (6) for communicating the air intake port (4) with the air discharge port (5), an indoor heat exchanger (9) having refrigerant tubes arranged in a plurality of stages and rows parallel with each other and disposed curvedly along the inner surface of the casing so as to face the air intake port (4), and a cross flow fan (7) disposed between the indoor heat exchanger (9) in the air flow path (6) and the air discharge port (5). The air flow path (6) includes a forward guide part (6a) which guides the air to the forward lower side and is gradually increased in its flow passage area toward the downstream side. The sum of the lengths of the upper wall (6b) and the lower wall (6c) of the air flow path (6) closer to the downstream side than the cross flow fan (7) is set to 3.5 times the diameter of the cross flow fan (7) or more.
