NON-SINTERED ELECTRODE AND METHOD OF MANUFACTURING SAME

摘要

A metal sheet (1) which constitutes a non-sintered type electrode support is processed to have minute irregularities on its surface. The irregularities are formed by a mechanical method such that protrusions (9) and indentations (8) are configured with a center-to-center pitch (P) in the range of from 50 to 300 mu m and such that the apparent thickness after processing is at least three times as large as the unprocessed material thickness.
