Abstract: A tablet PC case includes a first protective cover, a second protective cover, and a connection unit. The first protective cover includes a pair of retained frame portions. Each retained frame portion includes an outer surface portion and a first end face. The second protective cover includes a chassis, an input unit, a terminal group, and a magnet portion. The chassis includes a groove portion recessed from the front surface of the chassis. The groove portion includes a first groove in which one edge of the tablet PC can be retained, and a pair of second grooves in which the pair of retained frame portions is retained. The second groove includes a groove base surface like a curved concave surface in contact with the outer surface portion, and a second end face opposed to the first end face. The terminal group is disposed in the first groove.
