An indoor unit of an air-conditioning apparatus comprising: a casing having a suction port formed in an upper portion and a blow-out port formed on a lower side of a front surface portion; a plurality of fans; a heat exchanger provided on the upstream side of the blow-out port in the casing and configured to exchange heat between air blown out from the fans and a refrigerant; a horizontal wind direction control vane provided at the blow-out port and configured to control a horizontal direction of an airflow blown out from the blow-out port; a vertical wind direction control vane provided at the blow-out port and configured to control a vertical direction of the airflow blown out from the blow-out port; a control device; wherein an air volume, an orientation of the horizontal wind direction control vane, and an orientation of the vertical wind direction control vane of the fans are each controlled by the control device; wherein the horizontal wind direction control vane is divided into a plurality of horizontal wind direction control vanes, the orientations of which can be changed individually; the vertical wind direction control vane is divided into a plurality of vertical wind direction control vanes, the orientations of which can be changed individually, the number of the divided vertical wind direction control vanes being the same as the number of the divided horizontal wind direction control vanes, and the control device being capable of distributing airflows having different air volumes simultaneously to two different places in the room by an individual control of the orientations of the divided horizontal wind direction control vanes and of the divided vertical wind direction control vanes, and a control of the air volume of each of the fans, characterized in that it further comprises a human detection sensor, that is an infrared ray sensor, configured to acquire a heat image of a room and to detect a position of a person present in the room; the control device divides a floor surface area of the room into a plurality of area blocks and recognizes those area blocks in the room where a person is present, by replacing coordinate points of the heat image with the area blocks; said airflows distributed by the control device according to the detected results of the human detection sensor are directed to two separate of the area blocks, in which two persons are present; the fans are axial-flow or mixed-flow fans provided in parallel on the downstream side of the suction port in the casing and on an upstream side of the heat exchanger. a casing having a suction port formed in an upper portion and a blow-out port formed on a lower side of a front surface portion;
