摘要

It is an object of the present invention to provide a three-dimensional network porous aluminum body in which the amount of aluminum constituting a skeleton of the three-dimensional network aluminum aluminum body is uneven in the thickness direction, and a current collector and an electrode each using the aluminum porous body, and to provide a manufacturing method therefor. That is, in such a sheet-shaped aluminum three-dimensional network body for a current collector, the amount of aluminum constituting a skeleton of the three-dimensional network aluminum porous body is uneven in the thickness direction. In particular, in the case where a cross section is divided in the thickness direction of the three-dimensional network aluminum porous body into three regions, a region 1, a region 2 and a region 3 in this order, it is preferable that the average of the aluminum amounts in the Area 1 and in area 3 differs from an amount of aluminum in area 2.
