An indoor unit for an air-conditioning apparatus, comprising: an air-sending unit configured to send air subjected to heat exchange with refrigerant to an air-conditioning target space through an air outlet (2a to 2d), the air-conditioning target space being divided into a plurality of areas; an up-and-down airflow direction adjuster (4a to 4d) provided at the air outlet (2a to 2d), and configured to adjust an angle in an up-and-down direction of a blowing direction of the air sent through the air outlet (2a to 2d); a right-and-left airflow direction adjuster provided at the air outlet (2a to 2d), and configured to adjust an angle in a right-and-left direction of the blowing direction of the air sent through the air outlet (2a to 2d); a controller configured to control the angle of the up-and-down airflow direction adjuster (4a to 4d) and the angle of the right-and-left airflow direction adjuster ; and a human body position detection unit configured to detect whether or not a person is present for each of the plurality of areas into which the air-conditioning target space is divided, the controller being configured to control the up-and-down airflow direction adjuster (4a to 4d) and the right-and-left airflow direction adjuster to continuously change the angle in the up-and-down direction and the angle in the right-and-left direction such that the blowing direction of the air is switched to areas of the plurality of areas, the controller being configured to control the up-and-down airflow direction adjuster (4a to 4d) and the right-and-left airflow direction adjuster to operate in association with each other to cause the blowing direction of the air to be directed to areas, among the plurality of areas, detected by the human body position detection unit in which a person is absent. an air-sending unit configured to send air subjected to heat exchange with refrigerant to an air-conditioning target space through an air outlet (2a to 2d), the air-conditioning target space being divided into a plurality of areas; an up-and-down airflow direction adjuster (4a to 4d) provided at the air outlet (2a to 2d), and configured to adjust an angle in an up-and-down direction of a blowing direction of the air sent through the air outlet (2a to 2d); a right-and-left airflow direction adjuster provided at the air outlet (2a to 2d), and configured to adjust an angle in a right-and-left direction of the blowing direction of the air sent through the air outlet (2a to 2d); a controller configured to control the angle of the up-and-down airflow direction adjuster (4a to 4d) and the angle of the right-and-left airflow direction adjuster ; and a human body position detection unit configured to detect whether or not a person is present for each of the plurality of areas into which the air-conditioning target space is divided, the controller being configured to control the up-and-down airflow direction adjuster (4a to 4d) and the right-and-left airflow direction adjuster to continuously change the angle in the up-and-down direction and the angle in the right-and-left direction such that the blowing direction of the air is switched to areas of the plurality of areas, the controller being configured to control the up-and-down airflow direction adjuster (4a to 4d) and the right-and-left airflow direction adjuster to operate in association with each other to cause the blowing direction of the air to be directed to areas, among the plurality of areas, detected by the human body position detection unit in which a person is absent. <EOS>
