PROBLEM TO BE SOLVED: To smoothly make a concealed information holding body such as an information-concealed postcard, which prevents overlap-bonded surfaces from being accidentally peeled off from each other during handling. SOLUTION: Information common among the respective information-concealed postcards 41 is printed by printing machines 2a and 2b, while a continuous sheet 11, the front and back sides of which are precoated with a pressure-sensitive weak adhesive, is transferred in a prescribed direction. After various perforated lines for folding, cutting, etc. are formed by a perforated-line forming device 3, a through-hole is formed by a through-hole forming device 4. After individual information including the concealed information peculiar to each of the information-concealed postcards 41 is printed by a double-side printer 5, the coating nozzles 6a and 6b makes a pressure-sensitive firm adhesive applied to a surface-to-be-overlapped outside the perforated line for cutting, serving as a peel starting end when the overlap-bonded surfaces of the information-concealed postcard 41 are peeled off from each other. Subsequently, a folding device 7 makes the surfaces-to-be-overlapped folded on each other in such a manner as to overlap each other along the perforated line for folding, and each unit sheet 18 is cut by a cutting device 8. After that, an application device 9 makes the overlapped surfaces pressure-bonded together to form the information-concealed postcard 41. COPYRIGHT: (C)2007,JPO&INPIT
