PROBLEM TO BE SOLVED: To print contents, which are different from each other, to each thermal paper of a thermosensitive duplicating sheet and, at the same time, hide secret information printed on the thermal paper on a back surface side. SOLUTION: In the thermosensitive duplicating sheet 10, an information hiding part 110, which is a black solid printed portion, is formed in advance on a first thermal paper 11 of a first sheet in response to a secret information displaying part 120 on a second thermal paper 12 of a second sheet. In addition, when a result of acceptance or rejection is printed in the thermosensitive duplicating sheet 10 with a thermosensitive duplicating printer, energy, which can develop color in both the first thermal paper 11 and the second thermal paper 12, is applied into the printing range of the information hiding part 110. As a result, while the result of acceptance or rejection 121 is displayed in the secret information displaying part 120 of the second thermal paper 12, no result of acceptance or rejection is displayed due to the information hiding part 110 being already formed on the first thermal paper 11.
