And an object of the present invention is to provide a method for producing an aluminum plate and an aluminum plate having good coating properties and high adhesion to an active material. An aluminum plate having a plurality of through holes penetrating in the thickness direction, characterized in that the average opening diameter of the through holes is 0.1 占 퐉 or more and less than 100 占 퐉, and the maximum diameter (Ra) And has a through-hole A whose diameter Rb satisfies 1 > Rb / Ra > = 0.1. |
