PROBLEM TO BE SOLVED: To provide an assembled packaging box which is easily assembled and capable of reliably maintaining the assembled condition. SOLUTION: An inner side plate 6 which is continuously provided on a first side plate erected from a bottom plate is pinched by an erected second side plate and a folded-back folded-back plate 7. A hole part 10 penetrated in its thickness direction is formed in the inner side plate 6. An engagement piece 12 which can be oscillated in its thickness direction and slightly larger than the hole part is provided on the folded-back plate 7. After the folded-back plate 7 overlaps the inside of the inner side plate 6, the engagement piece 12 is pressed and oscillated in the thickness direction, and press-fitted in and engaged with the hole part 10 to maintain the folded-back condition of the folded-back plate 7.
