A packaging container that can be easily disassembled is provided at low cost. The packaging container is formed by a laminate including a base layer being folded into a box shape and each end thereof being overlapped to be sealed with each other, the laminate having a fragile part formed thereon. The laminate further has, for example, a film layer, and includes, as a fragile part, a first scored part formed on a base layer and a second scored part formed on a film in a 2.0-mm-wide band area with the first scored part being a widthwise center.
