PROBLEM TO BE SOLVED: To prevent left and right lateral plates from being deformed by a simple structure even when a packaged object moves during conveyance in a folding-type packaging box. SOLUTION: The folding-type packaging box 1 is provided with: a rectangular bottom plate 2, a pair of left and right lateral plates 3 and 4 continuous to the bottom plate 2, a front/rear pair of front and rear lateral plates 11 and 12 continuous to the bottom plate 2, a left-front flap 7 continuous to the left lateral plate 3 and bent toward the rear side of the front lateral plate 12, a right-front flap 8 continuous to the right lateral plate 4 and bent toward the rear of the front lateral plate 12, a front-top plate 13 continuous to the front lateral plate 12 and bent upward of the left-front flap 7 and the right-front flap 8, and a rear-top plate 15 continuous to the rear lateral plate 11 and covering the front-top plate 13 from above. Deformation-preventing bulged portions 30 which bulge upward from left and right lateral plates 3 and 4 and abut the rear surface of the front-top plate 13 when bent toward the rear side of the front lateral plate 12 are formed in the left-front flap 7 and the right-front flap 8.
