Abstract:
Provided are a three-dimensional net-like aluminum porous body in which the diameter of cells in the porous body is uneven in the thickness direction of the porous body; a current collector and an electrode each using the aluminum porous body; and methods for producing these members. The porous body is a three-dimensional net-like aluminum porous body in a sheet form, for a current collector, in which the diameter of cells in the porous body is uneven in the thickness direction of the porous body. When a cross section in the thickness direction of the three-dimensional net-like aluminum porous body is divided into three regions of a region 1, a region 2 and a region 3 in this order, the average cell diameter of the regions 1 and 3 is preferably different from the cell diameter of the region 2.
