To solve a problem that people always feel it inconvenient to find that, almost none of books, reference books, general datebooks, notebooks, etc. are accompanied with a string bookmark, and so they use a substitute for a bookmark by utilizing other substitutions, such as a small piece of cut paper or the like when they read and write, but the substitution of a bookmark hinders reading and writing and bothers them about a place to put it aside and related troubles.

A problem is easily solved by utilizing a bookmark (Fig.1) as follows. The bookmark can be quickly and very simply pasted to any place anytime, anywhere, as shown in Fig.3, and Fig.4 (not shown) by peeling off a rear-surface release paper (3), and can be used in the totally same state as a conventional bookmark.
