Summary:PROBLEM TO BE SOLVED: To expand a detection range of a human body detection sensor installed in a remote controller.SOLUTION: A toilet seat device includes a body 200 installed on a toilet bowl 110 and having an electric function built-in; and a remote controller 400. The remote controller 400 includes a human body detection sensor 300. The human body detection sensor 300 includes a pyroelectric sensor 310 having a light receiving surface 311, and a mirror 320 arranged in front of the light receiving surface 311 and having a reflecting surface for reflecting an infrared ray to be applied to the light receiving surface 311. The receiving surface 311 is arranged inside a surface of an outer shell of the remote controller 400, and part of the reflecting surface is arranged outside the surface of the outline. Accordingly, the light receiving surface 311 of the pyroelectric sensor 310 is allowed to directly receive the infrared ray emitted from a human body and receive the ray reflected on the reflecting surface of the mirror 320. As a result, a light-receiving range is expanded, and the detection range of human body is expanded.
