PROBLEM TO BE SOLVED: To provide a memory card system provided with an auxiliary battery and allowed to be applied to a photographing apparatus capable of performing photographing without missing a shutter chance even when the residual quantity of an exclusive secondary battery is reduced.

SOLUTION: A memory card system provided with a memory card 10, a sheet-like secondary battery 11 and a case 12 is manufactured. The sheet-like secondary battery 11 is stored in a storing part 120 in the case 12 so as to be folded and the memory card 10 is stored so as to be held in the folded secondary battery 11 to manufacture the compact memory card system 1. When the memory card system 1 is loaded in the photographing apparatus, the sheet-like secondary battery 11 is used as an auxiliary battery.
