Abstract: Provided are a metal foam stack and a manufacturing method thereof. The metal foam stack includes one or more stack units. The stack unit includes: a first metal foam sheet including an open cell, in which a plurality of internal cells is connected with one another; a first bonding member positioned on the first metal foam sheet; and a second metal foam sheet positioned on the first bonding member, and including an open cell, in which a plurality of internal cells is connected with one another. Materials of an interface between the first metal foam sheet and the first bonding member and an interface between the second metal foam sheet and the first bonding member are atomically diffused.
