Abstract
Provided are an electrode manufacturing apparatus and a method of manufacturing an electrode in which an electrode capable of preventing the occurrence of an internal short circuit is manufactured. A current collector is passed through a coating position in a downward direction by a reference roll. Thereby, just after coating of a mixture is interrupted, a built-up mixture between the current collector and a coating outlet is pulled in a downward direction by the current collector, so the position of the built-up mixture is lower than the position of the coating outlet. Therefore, the adhesion of the mixture to the coating outlet can be prevented, and as a result, a non-forming region where no mixture is formed can be prevented from being coated with the mixture.
