PROBLEM TO BE SOLVED: To provide an outer box for an inner bag for microwave heating which has a simple structure for reliably supporting an inner bag with a sufficient tilt angle when the inner bag is inflated by heating, and a packaging body for microwave heating having the same.SOLUTION: An outer box 1 includes: a front plate 2; a left side face plate 3a and a back face plate 4 which sequentially continue to a side 2c on the left side of the front plate 2 via fold lines; a right side face plate 3b which continues to a side 2d on the right side of the front plate 2 via fold lines; and a top face plate 5 and a bottom face plate 6 which continue to an upper side 2a and a lower side 2b of the front plate 2 via fold lines. First fold lines 13a, 13b comprising two creases extending in a direction to a lower side 4b of the back face plate 4 are formed on the back face plate 4 by using both end parts of a hinge line 9 as start points. When an inner bag is heated while being supported by the outer box 1, the outer box 1 bends at the first fold lines 13a, 13b by the inflation of the inner bag and is flexibly deformed in a thickness direction. |
