22 ABSTRACT A postcard comprises a postcard material and a covering material which is stuck to this postcard material and covers at least part thereof. This covering material comprises a base material which a heat adherent resin layer is formed on the main surface thereof and an adhesion retarding layer which is formed on the main surface of this heat adherent layer resin, and partially reduces the adhesive force of the above-mentioned postcard material to make it adhere weakly to the above-mentioned postcard material. Accordingly, at the portion of the adhesion retarding layer, the covering material can be peeled comparatively simply off the postcard material and various information formed on the main surface of the postcard material can be seen.
