To provide a storage tool provided with a function of preventing a stored card from falling out, and for which the card can be taken in and out through one action with less restrictions on design.

In the storage tool such as a card case or a wallet provided with a card storage part with at least one or more pockets 5 for taking the card C in and out, on a position adjacent to the exposed side of the card C stored in the pocket 5, a projecting stopper 8 to be parallel with the exposed side is provided. When the card C stored in the pocket 5 is to fall out, since the exposed side of the card C abuts on the stopper 8, the card is prevented from falling out when it is carried. At the time of taking the card C in and out of the pocket 5 of the card storage part, since the deflection of the storage tool itself is utilized and the operation of sliding the card over the stopper is sufficient, the card is taken in and out through one action.
