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 refresh and a display-switching of the electronic paper by utilizing the electrical power stored in the electrical storage part. The controller starts the refresh in a first state by performing a first determination determining whether or not the electrical power stored in the electrical storage part is in the first state. The electrical power stored in the electrical storage part in the first state is larger than electrical power necessary to complete the refresh.
