A method for manufacturing a negative electrode for a non-aqueous electrolyte secondary cell, which comprises forming a resist pattern having a great number of openings (12c) on one surface of a negative electrode (10) having an active material layer (2) containing an element having high ability to form a lithium compound, and then removing exposed regions through openings (12c) by etching, to form a great number of through holes (5) extending in the thickness direction into the active material layer (2), wherein the above resist pattern is formed by a lithography method or a printing method. The above method can be suitably used for forming through holes having a desired size with a desired arrangement pattern with ease, in a negative electrode for a non-aqueous electrolyte cell.
