The disclosed portable information terminal (10) is compact enough to be held in one hand, and when the device is being held in one hand by a user, the thumb of one hand placed on a display area (14) is detected by a transparent touch panel provided on the display area (14). At the time of detection, the terminal returns from standby mode, and therefore, a command will not be erroneously executed. Also, operation input is recognized resulting from a finger (aside from the thumb) approaching, touching, or pressing a touch panel (261) provided on the reverse side from the surface to which the display area (14) is provided, and a pre-associated process command is executed in response to the finger operation input that was recognized, and therefore, a suitable operation input interface for one hand is achieved.
