Abstract
A metal foil including: a steel layer whose thickness is 10 to 200 μm; an Al-containing metal layer arranged on the steel layer; and plural granular alloys which exist in an interface between the steel layer and the Al-containing metal layer, wherein, when a cutting-plane line of a surface of the Al-containing metal layer is defined as a contour curve and an approximation straight line of the contour curve is defined as a contour average straight line, a maximum point, whose distance from the contour average straight line is more than 10 μm, is absent on the contour curve, and wherein, when an equivalent sphere diameter of the granular alloys is x in units of μm and a thickness of the Al-containing metal layer is T in units of μm, the granular alloys satisfy x≦0.5T.
