A method of producing an electrode body includes obtaining a state in which an electrode active material layer in a wet state which includes a first solid component containing electrode active material particles and a first liquid phase component and which includes the first solid component at a weight ratio in a range of 70 to 85% is present on the collecting foil, and applying an insulating particle paint which includes a second solid component containing insulating particles and a second liquid phase component and which includes the second solid component at a weight ratio in a range of 35 to 50% onto the electrode active material layer in the wet state, wherein a surface tension value of the first liquid phase component is in a range of 90 to 110% of a surface tension value of the second liquid phase component.
