A mobile terminal includes a display unit and a touch unit located on a surface of the display unit. The display unit is configured to display a lock screen capable of setting a locked state in which execution of a predetermined processing based on a touch operation is restricted and capable of releasing the locked state through a touch operation performed on the touch unit while the locked state is set. The mobile terminal comprises at least one processor configured to: detect a touch operation performed on a predetermined area of the lock screen; and set, in a case where the detection module detects a touch operation performed on the predetermined area, an invalid area on the basis of the touch operation, the invalid area making a touch operation invalid.
