An air conditioner installed on a wall surface inside a room, the air conditioner including a suction port through which air inside the room is taken in, a blowout port through which the air taken in through the suction port and then conditioned is sent out into the room, a blowing passage through which the conditioned air is directed to the blowout port, and a wind deflector (110a, 110b, 111a, 111b, 112a, 112b, 113a, 113b, 113c, 114a, 114b, 115a, 115b) that permits a wind direction of the conditioned air sent out through the blowout port to be varied between a frontward-downward direction and a straight downward direction or a rearward-downward direction, whereby the blowing passage has a front guide that guides the conditioned air in a frontward-downward direction, and the front guide has an upper wall and a lower wall that are so inclined as to be increasingly low frontward, characterized in that a terminal end of the front guide is defined by a plane that passes through a position where a direction of inclination of the upper wall changes to horizontal or upward and that also passes through a position where a direction of inclination of the lower wall changes to straight downward, that, when the conditioned air is sent out through the blowout port in a straight downward direction or in a rearward-downward direction, the wind deflector (110a, 110b, 111a, 111b, 112a, 112b, 113a, 113b, 113c, 114a, 114b, 115a, 115b) is so arranged as to be continuous with a wall surface of the blowing passage to form a continuous pathway from the terminal end of the front guide to the front guide, a high static pressure part is formed in the pathway, and a terminal end of the pathway serves as the blowout port, that a width of the pathway in a direction substantially perpendicular to an air stream as seen from a side face is, throughout from the terminal end of the front guide to the blowout port, so maintained as to be larger than at the terminal end of the front guide, and that the high static pressure part is formed in contact with the wind deflector (110a, 111a, 112a, 113a, 113b, 114a, 114b, 115a, 115b) located in a frontward direction in which an air stream flowing through the front guide is flowing, a static pressure in the high static pressure part is higher than in the front guide, the high static pressure part has isobars running along a direction in which the conditioned air facing the wind deflector (110a, 111a, 112a, 113a, 113b, 114a, 114b, 115a, 115b) flows, the high static pressure part narrows a stream passage of the conditioned air so that a stream passage area in a thus narrowed part is smaller than at the terminal end of the front guide. a suction port through which air inside the room is taken in, a blowout port through which the air taken in through the suction port and then conditioned is sent out into the room, a blowing passage through which the conditioned air is directed to the blowout port, and a wind
