PROBLEM TO BE SOLVED: To provide a laminated confidential information concealment postcard with an unsealing detection function which does not need a sealer for repasting and furthermore detects the unsealing by a third party as well as eliminates release paper waste for pasting after printing or handwriting confidential information when used as a reply card and prevents the paper surface of the unsealing part from tearing when the recipient unseals. SOLUTION: The post card 10 with an attachment 30 connected to the card body 20 via a folding line a1 includes a narrow unreleasable strong press-bonding adhesive 70 on the right side end of the backside of the attachment 30. A knife edge 40 is formed on the just inner side of the strong press-bonding adhesive 70, and a weak press-bonding adhesive 60 is applied on the area excluding the strong press-bonding adhesive 70 on the back side of the post card 10.
