Abstract
A three-dimensional network aluminum porous body in which the amount of aluminum forming a skeleton of the three-dimensional network aluminum porous body is uneven in the thickness direction, and a current collector and an electrode each using the aluminum porous body, and a manufacturing method thereof. In such a sheet-shaped three-dimensional network aluminum porous body for a current collector, the amount of aluminum forming a skeleton of the three-dimensional network aluminum porous body is uneven in the thickness direction. For example, in the case where a cross section in the thickness direction of the three-dimensional network aluminum porous body is divided into three regions of a region 1, a region 2 and a region 3 in this order, each region is configured so that the average of the amounts of aluminum in the region 1 and the region 3 differs from the amount of aluminum in the region 2.
