    • An automatic insertion bookmark 10 designed to allow a bookmark portion 14 to be automatically inserted into and placed on an opened page 20a of a book 16. The bookmark 10 includes a fixing portion 12, a connecting portion 13, and a bookmark portion 14. The fixing portion 12 is either prefixed to one of the following or fixed thereto when the bookmark 10 is used: a back cover 18 of the book 16; a front cover 20 of the book 16; and, a leaf 19 of the book 16 in the immediate vicinity of either the back cover 18 or the front cover 20. A proximal end of the connecting portion 13 is connected to an upper portion of the fixing portion 12. Further, the bookmark portion 14 is connected to a distal end of the connecting portion 13. When the bookmark 10 is used, the bookmark portion 14 is folded downward at a portion where the bookmark portion 14 and the connecting portion 13 are joined together. As a result, the bookmark portion 14 is directed downward in an opposed relationship to the fixing portion 12.
