PROBLEM TO BE SOLVED: To provide an air conditioner capable of saving energy. SOLUTION: This air conditioner comprises an air intake port 4 for introducing the air in a room into a casing of an indoor machine 1, an air discharge port 5 formed at a 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 an 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 a forward lower side and is gradually increased in its flow passage area toward a downstream side, and the sum of lengths of an upper wall 6b and a lower wall 6c of the air flow path 6 closer to a downstream side than the cross flow fan 7 is set to 3.5 times a diameter of the cross flow fan 7 or more.
