PROBLEM TO BE SOLVED: To provide a paper bag whose mouth can be sealed by simple work by an operator of pressing a flap against the bag. SOLUTION: The paper bag 1 has the sealing flap 5 on its mouth 4. A nonadhesive coated face B is formed on a part of a paper bag surface 6 adjacent to the mouth 4. When the mouth 4 is folded toward the paper bag surface 6 with respect to an almost middle point of the nonadhesive coated face B, the flap 5 comes in contact with a part of the paper bag surface 6. An adhesive coated face S, which is coated with a one-touch type adhesive that glues together adhesive coated faces and does not glue an adhesive coated face to a nonadhesive coated face, is formed on the flap 5 and on the part of the paper bag surface 6 coming in contact with the flap 5.
