To provide metal foil of a new structure and a laminate having the metal foil and applicable to various uses.SOLUTION: Metal foil 10 has a waveform structure 11 that repeats a crest part 12 and a valley part 13 periodically. The waveform structure 11 has an opening 14 and a protrusion 15 protruding from the opening 14. The protrusion 15 protrudes toward the inside of the waveform structure 11. The crest part 12 and the valley part 13 extend in the longitudinal direction with a left oblique region 24 inclined in left oblique to the longitudinal reference line and a right oblique region 25 inclined in right oblique to the longitudinal reference line repeated alternately. Some pieces of the metal foil 10 or the metal foil 10 and a sheet body such as lath metal are stacked in the thickness direction to constitute a laminate.SELECTED DRAWING: Figure 1 【課題】新たな構造を備えたメタル箔の提供と、同メタル箔を備えると共に種々の用途に適用することができる積層体の提供を図る。【解決手段】メタル箔１０は、山部１２と谷部１３とが周期的に繰り返す波形構造部１１を備える。波形構造部１１は開口部１４と、開口部１４から突出する突出部１５を備える。突出部１５は、波形構造部１１の内側に向けて突出しているものである。山部１２と谷部１３は、縦基準線に対して左斜めに傾斜する左傾斜領域２４と右斜めに傾斜する右傾斜領域２５とが交互に繰り返されて縦方向伸びている。このメタル箔１０は、メタル箔１０同士又はラスメタルなどのシート体と厚み方向に重ねられることにより積層体を構成する。【選択図】図１
