To provide a sanitary device capable of clearly making separate use of a receiving window for receive of signals from a remote control device and a human body detection sensor.

The human body detection sensor window 27 and the remote control receiving window 26 are constituted of the same member (smoke top 1), but as the window section is divided by a case cover 2, the use of the receiving window can be made clear. When a name is indicated in the vicinity of each window or a title is written in a use manual, the usability is further enhanced.
