A remote control device according to an embodiment includes an operation button, a generator, an electrical storage part, electronic paper, and a controller. The operation button is for remotely operating a wet-area device. The generator generates electrical power by utilizing energy when the operation button is pressed. The electrical storage part stores the electrical power. The electronic paper displays a setting state of the wet-area device. The controller controls a display-switching of the electronic paper and a transmission of a signal to remotely operate the wet-area device. The operation button is for modifying the setting state. The controller performs the display-switching and the transmission of the signal by utilizing the electrical power stored in the electrical storage part. The controller performs the display-switching after the transmission of the signal when the operation button is pressed.
