PROBLEM TO BE SOLVED: To provide a hiding postcard, in which a written content can be hidden by pasting a hiding paper piece so as to cover personal information or the like written in a postcard main body piece therewith, at the same time, which has no fear for peeling the hiding paper piece off the postcard main body piece even during its handling on the way of mailing, which left the confirmable fact of a surreptitious glance when information written in the postcard is unsealed and surreptitiously glanced by a third person before the mailed postcard is handed to a receiver, resulting in surely keeping the secret of the written content. SOLUTION: In the hiding postcard, in which the postcard main body piece and the hiding paper piece are connected with each other through a folding line and a transparent sheet having a transparent self-adhesive layer on its top surface and a releasing paper are piled up through a releasant layer and an adhesive layer on the hiding paper piece in the order named, an unsealing perforation with a predetermined width from the end edge is formed in the hiding paper piece and, at the same time, stronger bonding parts are provided at respective portions on the end edge sides of the hiding paper piece so as to directly bond the end edge of the hiding paper piece with that of the transparent sheet.
