Abstract

A negative electrode (22) for a power storage device includes a negative electrode current collector (22a) including a first surface (22a1), and a negative electrode active material layer (22b) formed on the first surface (22a1) of the negative electrode current collector (22a). The weight per unit area of the negative electrode active material layer (22b) is 20 mg/cm<2> or greater. The negative electrode active material layer (22b) contains graphite, an aqueous binder having a glass transition temperature less than 7°C, and single-walled carbon nanotubes.
