<p>An air conditioner is provided in the indoor unit with: an obstacle detection device (30) for detecting whether or not there is an obstacle and also detecting whether the obstacle is large or small; and a left-right vane (14) for changing the air blowing direction to the left and right. When it is determined on the basis of the result of the detection by the obstacle detection device (30) that the region to be air conditioned includes multiple obstacle regions in which obstacles are present, the air conditioner controls the left-right vane (14) to perform air flow control for blowing air toward an obstacle region in which a small obstacle is present.</p>
