PURPOSE: A pizza packaging box is provided to avoid the shape of pizza from being crushed by slanting when transported in a quadrangle or octagonal box. CONSTITUTION: A bottom board(2) is made in a round shape. Circumferential lateral sides are made around the circumference of the bottom board. Cylindrical lateral sides are made by raising lateral boards(3) on the circumferential lateral sides. The lateral boards are surrounded by five foldable boards(8) from the bottom board, and fixed by inserting convex grooves(9) into concave grooves(10). A cover board(11) is fixed by placing the cover board over a main body and fitting foldable wings(12).
