Summary:PROBLEM TO BE SOLVED: To enhance bonding strength of a collector and an electrode mixture by enhancing followability of the electrode mixture to the collector surface when a high solid electrode mixture is applied.SOLUTION: In a method of manufacturing a secondary cell 1, a slurry electrode mixture obtained by kneading an electrode material and a solvent is arranged on a collector foil 40 as a collector, and electrode layers 42A and 42B are formed on the collector by volatilizing solvent from the electrode mixture. High solid content slurries 21A and 21B having different solid contents are applied to respective faces of the collector having multiple through holes 41.
