PROBLEM TO BE SOLVED: To provide a packaging container joining structure capable of joining a packaging container without using any metallic member, a double-sided adhesive tape, an adhesive or the like, omitting any special manufacturing device, and reliably performing the positioning, and usable as a recycling material. SOLUTION: A stepped part with a tip side of a circumferential side frame being lower is provided on the inner side forming a bottom plate side of an outer end. In the stepped part, a wall face formed in the thickness direction is formed on an inclined part with the bottom plate direction being inclined to the tip side. A recessed part is formed on the outer end at the position separated from the stepped part in the longitudinal direction of the circumferential side frame. In addition, a recessed part and a projecting part to be matched in a shape of the recessed part with the stepped part on the outer end are formed on the inner circumferential side frame to constitute the other side of the joined part. An inclined part brought into contact with the inclined part of the stepped part of the outer circumferential side frame is formed in the recessed part, and the projecting part is engaged with the recessed part at the outer end.
