1. A metal porous body having a framework of a three-dimensional network structure,
the framework formed of a metal film and the framework having an interior that is hollow, wherein the metal film has an average thickness of 1 μm or more and 300 μm or less,
the metal film containing titanium metal or titanium alloy, a content of the titanium metal or the titanium alloy of the metal film being 90 mass % or more,
the metal porous body has a sheet shape, the sheet shape having a predetermined length in a length direction, a predetermined width in a width direction, and a predetermined thickness in a thickness direction,
the sheet shape is divided into at least two regions in the thickness direction of the sheet shape,
the at least two regions composed of the titanium metal or the titanium alloy of the metal film, the content of the at least two regions composed of the titanium metal or the titanium alloy of the metal film being 90 mass % or more,
a boundary separates each of the at least two regions in the thickness direction of the sheet shape, and
one or both of an average pore diameter of the metal porous body and a weight of the metal porous body is different between the at least two regions, the weight being a mass per unit area.
