Abstract
A process for producing an aluminum electrode foil for a capacitor, which includes a first step of preparing an emulsion from a mixture including a first phase of a liquid resin or a resin solution obtained by dissolving a resin in a solvent, a second phase of a liquid that is incompatible with the first phase, and an emulsifier; a second step of coating the emulsion on a surface of an aluminum foil; a third step of removing the second phase to form a resin film having a plurality of pores on its surface; a fourth step of etching the aluminum foil having the resin film formed thereon; and a fifth step of removing the resin film after etching. The production process can form high-density etching pits with high accuracy.
