To provide a packing box that can suppress deformation due to compression load.SOLUTION: A packing box 1 includes: a pair of side walls 10,11 facing a first direction; a pair of end walls 12,13 which have higher compression strength than the side walls 10,11 and face a second direction intersecting the first direction; first upper flaps 20,21 continuously provided on the upper end parts of the side walls 10,11 via a first upper folding line L2;second upper flaps 22, 23 continuously provided on the upper end parts of the end walls 12, 13 via a second upper folding line L3; first lower flaps 30,31 continuously provided on the lower end parts of the side walls 10,11 via a first lower folding line L4; and second lower flaps 32, 33 continuously provided on the lower end parts of the end walls 12, 13 via a second lower folding line L5. The first upper folding line L2 and the first lower folding line L4 are formed as if caving in toward the center parts of the side walls 10,11, and the second lower folding line L5 is formed as if protruding toward the direction away from the center parts of the end walls 12, 13.SELECTED DRAWING: Figure 1 【課題】圧縮荷重による変形を抑制することができる包装箱を提供する。【解決手段】包装箱１は、第１方向に対向する一対の側壁１０，１１と、側壁１０，１１よりも高い圧縮強度を有し、第１方向に交差する第２方向に対向する一対の端壁１２，１３と、側壁１０，１１の上端部に第１上折曲線Ｌ２を介して連設されている第１上フラップ２０，２１と、端壁１２，１３の上端部に第２上折曲線Ｌ３を介して連設されている第２上フラップ２２，２３と、側壁１０，１１の下端部に第１下折曲線Ｌ４を介して連設されている第１下フラップ３０，３１と、端壁１２，１３の下端部に第２下折曲線Ｌ５を介して連設されている第２下フラップ３２，３３と、を備え、第１上折曲線Ｌ２と第１下折曲線Ｌ４は、側壁１０，１１の中心部に向かって窪むように形成され、第２下折曲線Ｌ５は、端壁１２，１３の中心部から離れる方向に突き出すように形成されている。【選択図】図１
