Abstract
An air-conditioning apparatus includes a drain pan that receives water, and a detector including an ultrasonic sensor that emits and receives ultrasonic waves. The detector analyzes a response signal from the ultrasonic sensor to detect a contaminant generated in the drain pan. A bottom flat surface portion that forms a bottom of the drain pan is located parallel to a flat surface portion that forms a receiving surface of the ultrasonic sensor.
