Abstract
Provided is a composition for an electrochemical device functional layer with which it is possible to form a functional layer for an electrochemical device that can impart excellent process adhesiveness and blocking resistance to an electrochemical device member such as an electrode or a separator and that can cause an electrochemical device to display excellent electrochemical characteristics. The composition for an electrochemical device functional layer contains a particulate polymer and a binder. The particulate polymer has a molecular weight distribution (weight-average molecular weight (Mw)/number-average molecular weight (Mn)) of not less than 1.0 and not more than 3.0.
