It could be broken, and even if pulled out, the adhesive adhered to the edges, and it could not be said that it was good both visually and tactilely.

[0005]

SUMMARY OF THE INVENTION In view of the foregoing, the present invention has been made as a result of diligent study, and has a plurality of sheets stacked on the inside of a folded cover. In a booklet including an easy-separation part, an adhesive layer on the inner side of the spine, and a weak adhesive means enabling easy detachment between the adhesive layer and a plurality of sheets of the easy-separation part are interposed. Yes, furthermore, in a booklet including an easy release section in which a plurality of sheets are stacked,
An adhesive layer that binds one side of a plurality of sheets and a weak adhesive means that allows easy detachment are interposed between the adhesive layer and the plurality of sheets of the easy detachment unit.

[0006]

According to the present invention, the adhesive layer between one side of the easily detachable portion where the plurality of sheets are bound and the inner side of the spine is provided with a weak adhesive means for allowing easy detachment. Or, the weak detachment means that allows easy detachment is interposed between one side of the easily detachable portion where the plurality of sheets are bound and the adhesive layer, so that the booklet is in a reliable shape. Keeping and applying force to the sheet with the intention of detaching any sheet,
It can be detached with an appropriate force, and further, does not cause adhesive or the like to adhere to the edges.
