摘要

The purpose of the present invention is to provide a novel technology related to electrochemical elements, which enables an electrochemical element to exhibit excellent high temperature storage characteristics, while sufficiently ensuring adhesion of a functional layer and safety of the electrochemical element. Each one of composite particles for electrochemical element functional layers according to the present invention is provided with: a core particle which contains a melamine compound; and a shell polymer which covers at least a part of the outer surface of the core particle, while having at least one group that is selected from the group consisting of a nitrile group, a carboxylic acid group, a hydroxyl group, a sulfonic acid group, an aldehyde group and an amide group.
