Abstract
A dispersant composition for an electrochemical device contains a polymer including a nitrile group-containing monomer unit and an alkylene structural unit. Upon measurement of the polymer contained in the composition by dynamic light scattering, a value (A) detected for volume-average particle diameter D50 is not less than 50 nm and not more than 800 nm, and one or more peaks are detected in a particle diameter range of not less than 5 μm and not more than 30 μm.
