When a unit lock member (130) is engaged with a SIM card (220) mounted in a unit retention mechanism (120), a battery pack (210) can be mounted or removed. When the battery pack (210) is removed, the unit lock member (130) is permitted to slide thereby enabling mounting or removing the SIM card (220). Thus, the SIM card (220) cannot be mounted or removed while the battery pack (210) is mounted. Still, the battery pack (210) and the SIM card (220) are separately located in a plane, and hence a terminal main body (110) can be made thinner, and the presence of the SIM card (220) can be confirmed without the need to remove the battery pack (210).
