<p>Disclosed is a binder for electrochemical cell electrodes which is composed of an emulsion composition wherein resin particles each composed of an olefin polymer (A) and an acrylic polymer (B) having an internally crosslinked structure are dispersed in water. The binder for electrochemical cell electrodes exhibits sufficient adhesion to a metal collector, a positive electrode active material and a negative electrode active material, and enables to improve high-rate discharge characteristics and cycle characteristics.</p>
