The present invention relates to a method for producing an aluminum plate and an aluminum plate which have good coatability and high adhesion to an active material. In the aluminum plate having two or more through holes penetrating in the thickness direction, the through hole has an average opening diameter of 0.1 μm or more and less than 100 μm, and the aluminum plate has a through hole A having a shape that is internally formed. The shape of the maximum diameter Ra, the maximum diameter Ra and the minimum diameter Rb satisfy 1>Rb/Ra≧0.1. |
