    Abstract: The present application provides a method for preparing a metal foam. The present application provides a method which can freely control characteristics, such as pore size and porosity, of the metal foam, prepare the metal foam in the form of films or sheets which have conventionally been difficult to produce, particularly the form of thin films or sheets as well, and prepare a metal foam having excellent other physical properties such as mechanical strength. According to one example of the present application, it is possible to efficiently form a structure in which such a metal foam is integrated on a metal base material with good adhesive force.
