To provide an air conditioner 1 that includes an outdoor device and an indoor device and performs air conditioning inside a room. The indoor device includes a control unit, a storage unit, and an infrared sensor unit that detects a human by detecting infrared rays. The infrared sensor unit includes thermal-image acquisition elements that detect infrared rays to acquire thermal image data, and a sensor control unit that controls the thermal-image acquisition elements. At a time of reception of the thermal image data transmitted from the infrared sensor unit, the control unit determines whether an error has been occurred in communication for each of the thermal-image acquisition elements. The control unit sets a thermal-image acquisition element whose sum of number of times of determination that an error has occurred in the communication is equal to or larger than a certain number, as a communication-error established element. The control unit performs setting of not acquiring the thermal image data from the thermal-image acquisition element set as the communication-error established element.
