An aerosol including an active material powder, a binder, and a gas is prepared. An electric field is formed between a substrate and a porous electrode. The aerosol is electrically charged. The aerosol after the electrically charging is introduced into the electric field. The aerosol passes through the porous electrode and thereby the aerosol is introduced into the electric field. At the time of the aerosol passing through the porous electrode, the aerosol comes into contact with the porous electrode and thereby the aerosol is electrically charged. In the electric field, the aerosol after the electrically charging flies toward the substrate due to electrostatic force. The aerosol adheres to a surface of the substrate and thereby an active material layer is formed.
