A method of manufacturing a metal foam stack is provided. According to the present invention, the method includes: a metal foam sheet preparing step of preparing a plurality of metal foam sheets having a predetermined size and shape; a slurry application step of applying a slurry on a surface of the metal foam sheet; a metal foam stack forming step of forming the metal foam stack by stacking the metal foam sheets in a block form; a pressing force application step of applying pressing force having a predetermined magnitude to the metal foam stack; a pressing force removing step of removing pressing force applied to the metal foam stack after the pressing force application step is performed; and a heat treatment step of performing heat treatment of the metal foam stack to strongly attach the metal foam sheets to each other after pressing force applied to the metal foam stack is removed in the pressing force removing step.
