PROBLEM TO BE SOLVED: To prevent a coin from dropping through an opening, and to take out and put in the coin quickly even without providing a claps or a fastener by making a folding coin case big and thin. SOLUTION: A front cover 2 touching a bottom face 4 is made low in height, side covers 3, 3' are formed in an inverted T shape, and a top side 9 is made as high as and as long as the front cover 2. The top sides 8 of the side covers 3, 3' are made as high as or lower than the top side length of the front cover 2 even when the height of the top side 8 of the side cover 3 and the height of the top side 8 of the side cover 3' are added. Thus, the top side 8 of the side cover 3 and the top side 8 of the side cover 3' either touch or have a gap therebetween.
