PROBLEM TO BE SOLVED: To provide postcard paper which can be mailed under condition that information written on a postcard cannot be simply seen by a third person. SOLUTION: The postcard paper consists of foldable paper for preparing the postcard and two sheets of releasable paper pasted releasably on the foldable paper. In the foldable paper, a first piece of paper having an address writing part on the surface, a second piece of paper positioning at the center, and a third piece of paper on which characters of the postcard are displayed along the perforation for folding are continuously connected in the horizontal direction through two perforations for folding formed in the vertical direction. The width dimension of the first piece of paper has a shorter dimension than the width dimensions of the second piece of paper and the third piece of paper so that when the foldable paper is folded into three in a mirror-like fold, the characters of the postcard displayed on the third piece of paper can be visually seen. Adhesive layers becoming releasable after adhering are formed on the back faces of the first and third pieces of paper, and the releasable papers are pasted releasably respectively on the adhesive layers formed on the back faces of the second and third pieces of paper.
