A novel battery case for a portable terminal unit includes a first battery storage case monolithically integrated with the basic body of the portable terminal unit for accommodating two batteries within an opening thereof, the batteries being arrayed in parallel in one step. A second battery storage case in which two batteries can be set within an opening thereof, the batteries being arrayed in parallel in a separate step, is also provided. The second storage case can be mounted onto the basic body of the portable terminal unit so that the opening of the first battery storage case will be opposite to the opening of the second battery storage case.
