To improve cushioning effect for a packaged object without causing cost increase and prevent positional shift of cushioning members without causing lowering of the strength and durability of a packaging box, a packaging material includes a packaging box and cushioning members, a bottom panel and a cover panel of the packaging box being made of inwardly bendable inner flaps and outer flaps respectively, each of the inner flaps being provided with at least a through hole, the cushioning members being provided in inner side surfaces thereof with recesses in which corner portions or side portions of an object to be packaged are fitted, and on outer side surfaces thereof with cushioning projections fitted in the through holes of the inner flaps, the length of the cushioning projections being set larger than the thickness of the inner flaps so as to form a clearance between the inner flaps and cushioning projections when the cushioning members are housed in the packaging box.
