Abstract
A manufacturing method of middle member structure includes steps of applying an external force to a plate body to shape the plate body and form multiple recessed/raised structures and perforating the plate body to form multiple perforations misaligned from the recessed/raised structures so as to achieve a plate body with recessed/raised structures. The middle member structure is applicable to a vapor chamber to enhance the vapor-liquid circulation effect and the support for the internal chamber.
