The lower front case has a keyboard unit mounted therein. A bottom part extends in a front-rear direction of the lower front case. A key supporting part is formed such that it rises from the rear of the bottom part of the lower front case and extends in the key arrangement direction, and supports each of the keys of the keyboard unit at a base end of the key. A stopper body is formed such that it rises from the front of the bottom part of the lower front case and extends in the key arrangement direction, and stops a free end of each of the keys of the keyboard unit when the key is operated. A battery case is formed by six battery terminal-associated parts arranged side by side for batteries between the key supporting part and the stopper body.
