An integral packing paper box is provided to facilitate assembly work by forming the shape through a bending process without using an adhesive tape and to prevent the bottom surface from being torn out although heavy objects are stored in the packing box, by securing great durability against vertical load by integrally connecting the bottom surface and an upper surface. An integral packing paper box for storing and packing the content in an inner space formed by unfolding a bottom surface(21) and an upper surface(23) as one paper is composed of a box body unit(10) having front, rear, left, and right surfaces(11,12,13,14) formed on the straight line about a folding line and an adhesive part(15) formed on the left extension line of the front surface; a box closing unit(20) disposed at the upper end of the front surface of the box body and formed by integrally connecting the bottom and upper surfaces by a center connecting surface(22); and a fitting surface(24) integrally formed at the upper end of the upper surface of the box closing unit to fix the box closing unit to the box body. The box closing unit is not pulled out from the box body easily by curving the fitting surface to make the horizontal length of the fitting surface longer than that of the upper surface.
