To provide an automatic door device having a failure monitoring function capable of pursuing not only a failure part but also the cause of a failure, and capable of extracting information on the failure even if a CPU for executing a self-diagnosable mechanism causes a failure.

This automatic door device opens or closes a door by driving a motor of a door opening-closing mechanism by a controller on the basis of signals outputted from sensors by detecting the presence of an object by the sensors, and is characterized in that it has the CPU 26 for extracting detecting state information for indicating a detecting state of the sensors 15, 16, and 17 and door state information for indicating a door opening-closing state in the detecting state of the sensors as operation information from the controller 21, and a storage device 28 for successively storing the operation information extracted by the CPU 26 with the lapse of time.
