To provide a concealed postcard the concealment work of which a sender deals with is simple and the manufacturing cost of which is reasonable.

The postcard is made of the postcard body 2 whereupon the recipient information 6 and the personal information entry area 7 to fill in the sender's personal information are printed, and the concealing cover piece 5 which contacts the postcard body 2 via the folding line 3 to be turned up toward the postcard body 2 side at the folding line 3 and is pasted onto the postcard body 2 in the state of covering the personal information entry area 7, and thus the postcard prevents the leakage of the personal information of the sender.
