To provide a packaging case which facilitates the removal and storage of an attachment.

A hole 20C is formed by folding an inner lid 30, which is made by incising a part of a back face board 20, into a mount 3. An instruction manual 6 is put in and taken out of the packaging case 1 through the hole 20C, using the inner lid 30 as a guide board. When the instruction manual 6 is put in the packaging case 1, the vicinity of the right end of the instruction manual 6 is held between the inner lid 30 and a peripheral part 20F, and the instruction manual 6 is covered with an outer lid 16. In this manner, the instruction manual 6 can be easily put in the packaging case 1 to prevent undesired dropping off of the instruction manual 6, and can be easily taken out of the packaging case 1.
