An air conditioner comprising: a front panel that is configured to cover a front surface of a body housing and is openably and closably provided so as to be opened up about a hinge portion provided at an upper side of the front panel as an axis; characterized in that the air conditioner further comprises: an openable/closable panel that is mounted on the front panel to be capable of being opened and closed with respect to the front panel; and opening/closing mechanisms that are configured to open and close the openable/closable panel between a closed position where the openable/closable panel closes an intake opening of the front panel and an open position where the openable/closable panel is opened forward so as to be tilted forward with respect to the front panel, wherein the opening/closing mechanisms include slide rails that are provided on both side portions of the front panel and extend in a vertical direction, fixed pivot parts that are provided above the slide rails, sliders that are provided so as to be slidable along the slide rails and include movable pivot parts and rack gears, upper pivot parts and lower pivot parts that are provided on both side portions of the openable/closable panel, upper links that connect the fixed pivot parts to the upper pivot parts, lower links that connect the movable pivot parts to the lower pivot parts and are shorter than the upper links, intermediate links that connect intermediate pivot parts, which are provided at intermediate portions of the upper links, to the movable pivot parts, and drive units that include pinion gears meshing with the rack gears of the sliders. a front panel that is configured to cover a front surface of a body housing and is openably and closably provided so as to be opened up about a hinge portion provided at an upper side of the front panel as an axis;
