A suitcase and a manufacturing method thereof are disclosed. An upper case shell and a lower case shell are obtained, and a flexible material is fixedly connected to the upper case shell and the lower case shell. When the suitcase is assembled, elastic parts are compressed to install two ends of rods on installation parts of the upper case shell and the lower case shell, and a resilience force from the elastic parts is applied to the rods to drive the upper case shell and the lower case shell to be away from each other, and the flexible material connected to the upper case shell and the lower case shell is driven by the upper case shell and the lower case shell to be tensioned.
