Abstract
A manufacturing method and a manufacturing apparatus for a separator layer-coated electrode are provided capable of shortening the time required to cut out a separator layer-coated electrode with a laser beam. In a cutting process, a laser beam is irradiated to a laser irradiation target portion of a strip-shaped separator layer-coated electrode from a front-side separator layer side to cut a strip-shaped separator layer-coated electrode. Prior to the cutting process, a preheating process is conducted to preheat the front-side separator layer in the laser irradiation target portion.
