<p>In this portable terminal, a rear case has: a protruding portion (200), which has an inner wall of an opening and an end surface (201) on a same plane, and has an end surface (202) between the circumferential edge of the opening and an outer edge of the rear case; and a groove portion (300), which is adjacent to the protruding portion (200) in the direction along the opening, and is recessed from the inner wall (P) of the opening to a position between the circumferential edge of the opening and the outer edge of the rear case. A front case has: a protruding portion (210), which has the inner wall of the opening and an end surface on the same plane, and has an end surface between the inner wall of the opening and an outer edge of the front case; and a groove portion (310), which is adjacent to the protruding portion (210) in the direction along the opening, and is recessed from the inner wall of the opening to a position between the circumferential edge of the opening and the outer edge of the front case. The protruding portions and the groove portions are fitted in each other such that a wall surface (302) and the end surface of the protruding portion (210) are in contact with each other, and that a wall surface (312) and the end surface of the protruding portion (200) are in contact with each other.</p> |
