PROBLEM TO BE SOLVED: To provide a paper bag with an opening guide capable of easily forming an opening without using a knife or other cutting tools, preventing contents from scattering when discharging, and discharging only a required amount of the contents to store the remainder. SOLUTION: The paper bag formed by sealing the lower end and the upper end of a paper tube filled with the contents has an easily cuttable part 20, which serves as a guide to make an opening, formed on regions 13 and 14 corresponding to gussets of the bag 10. To prevent the part 20 from being broken before cutting the bag open, paper materials constituting the paper bag 10 are stuck to each other via a pasting part 24. A plurality of pasting parts 24 are provided in the width direction of the gusset-corresponding regions 13 and 14 of the bag 10 at necessary intervals. The easily cuttable part 20 can be formed at a position between the pasting parts 24 or a position where the parts 24 overlap. The easily cuttable part 20 preferably includes a main easily cuttable part 21 with a length extending over an approximately full width of the gusset-corresponding regions 13 and 14 of the paper bag 10 and a guide part 22 for guiding the cut to the main part 21.
