The present invention provides an operation panel 13 that makes it easier to select setting buttons 20c and 20e desired by a user and to perform setting of various kinds of processings, and an electric device including the same. The operation panel 13 provided in an image processing apparatus 1 includes an operation section 13a for inputting an operation instruction, a display section 13b for displaying an operation screen, a control section 13c for causing the display section 13b to display a different operation screen every time setting buttons 20c and 20e in the operation screen are operated, and a storage section 13d for storing the selected setting button 20c. The control section 13c counts the number of use times of each setting button 20c to store in the storage section 13d. When a setting screen is displayed, the control section 13c detects the number of use times of each of the setting buttons 20c to change a display state on the display section 13b depending on the number of use times. With the structure above, even when many setting buttons 20c and 20e are displayed on the setting screen for various kinds of processings, the desired setting button 20c can be selected easily.
