PROBLEM TO BE SOLVED: To obtain a book-bound matter, in which favorable visibility can be ensured on a photograph 8 or the like under the condition that the spread angleθof a leaf 6 is fully 180 degrees or on the photograph 8 or the like printed especially larger so as to cross a fold 9. SOLUTION: In the book-bound matter, in which a doubled leaf 6 is pasted so as to cross between mounting paper 7 adjacent to each other such as an album 1, respective leaves 6 are so arranged that a gap develops between the mounting paper 7 and 7 adjacent to each other being pasted with the leaves 6 when the respective leaves 6 are spread and the fold 9 of the doubled leaves 6 are made to project beyond the back end edges 11 of the respective mounting paper 7 to a back cover 3 side when the book-bound matter is closed.
