## Abstract

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 generated by the generator; 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 operation button is marked with information showing a function of the operation button. The controller performs the refresh in the case where the function is not realized when the operation button is pressed.

## Claims

### Claim 1

A remote control device, comprising:
an operation button for remotely operating a wet-area device;
a generator generating electrical power by utilizing energy when the operation button is pressed;
an electrical storage part storing the electrical power generated by the generator;
electronic paper displaying a setting state of the wet-area device; and
a controller controlling a refresh and a display-switching of the electronic paper by utilizing the electrical power stored in the electrical storage part,
the operation button being marked with information showing a function of the operation button,
the controller performing the refresh in the case where the function is not realized when the operation button is pressed.

### Claim 2 (depends on 1)
