PROBLEM TO BE SOLVED: To provide a thread sewing booklet, in which the recycling of stacked sheets can be easily performed and thread sewing is easily done and the manufacturing cost of which can be reduced. SOLUTION: The nearly central part of the stacked sheets 12, which is formed by stacking a large number of paper sheets 12a, is bound up with a cotton binding thread 13. Not bound-up parts 15 and 16 are formed at the back of the stacked sheet 12 between both the ends of the binding thread 13 and the end edges 12b and 12c of the laminating sheet 12. Since no thread end at both the ends of the binding thread 13 exposes itself outside, there is no maring of the exterior appearance of the booklet. In addition, since no outside exposure of the ends of the thread develops under the closed state of the booklet, no fraying of the tail end thread develops. COPYRIGHT: (C)2006,JPO&NCIPI
