The present invention makes it possible to manufacture a sheet-like composite that is excellent in mechanical properties such as bending resistance and can exhibit excellent output characteristics and cycle characteristics in a secondary battery by a simple manufacturing process. A method for producing a composite for a secondary battery electrode is provided. A carbon nanotube includes a step of preparing a dispersion by mixing a carbon nanotube, an electrode active material, and a solvent, and a step of forming a sheet-like composite by removing the solvent from the dispersion. Is a method for producing a composite for a secondary battery electrode, wherein the average diameter (Av) and the standard deviation of diameter (σ) satisfy the relational expression: 0.20 <(3σ / Av) <0.60.
