A touch pad includes: a center button region; a first button region disposed adjacent to the center button region; a second button region disposed adjacent to the center button region on the opposite side of the first button region; a load sensor configured to detect load at least at the center button region, the first button region and the second button region; and a controller configured to determine a detection by the load sensor of load of a first upper-limit value or higher at least at one of the first and second button regions as a depressed state, and determine a detection by the load sensor of load of a second upper-limit value or higher at the center button region as a depressed state. The second upper-limit value and the first upper-limit value are different. Particularly, the second upper-limit value is larger than the first upper-limit value.
