Abstract

Provided is an electrode sheet manufacturing method including preparing a sheet stack including an electrode composite material layer and a separator provided on the electrode composite material layer, irradiating the separator of the sheet stack with a first laser beam having a wavelength to be absorbed by the separator, and moving an irradiation position of the first laser beam relative to the sheet stack. The method further includes irradiating the sheet stack having been irradiated with the first laser beam with a second laser beam having a wavelength to be absorbed by the electrode composite material layer, and moving an irradiation position of the second laser beam relative to the sheet stack, wherein the irradiation position of the second laser beam moves so as to follow a track of the irradiation position of the first laser beam.
