Provided is a paste for a secondary battery that can cause an electrode mixed material layer to display excellent adhesiveness and can reduce internal resistance of a secondary battery. The paste for a secondary battery contains a conductive additive, a polymer, and a dispersion medium. The conductive additive includes one or more carbon nanotubes having a surface acid content of not less than 0.01 mmol/g and not more than 0.15 mmol/g, a surface base content of not less than 0.005 mmol/g and not more than 0.500 mmol/g, a ratio of the surface acid content relative to the surface base content of not less than 1.3 and not more than 3.0, and a specific surface area of 150 m/g or more.
