Abstract

A positive electrode (21) for a power storage device comprises: a positive electrode current collector (21a) that has a first surface (21a1); and a positive electrode active material layer (21b) that is formed on the first surface (21a1) of the positive electrode current collector (21a). The positive electrode active material layer (21b) contains a positive electrode active material that can store and release charge carriers. The basis weight of the positive electrode active material layer (21b) is greater than 50 mg/cm<2>, and the positive electrode active material content in the positive electrode active material layer (21b) is 97 mass% or more. The positive electrode active material layer (21b) contains an aqueous binder with a glass transition temperature of less than 7°C, and single-walled carbon nanotubes.
