<P>PROBLEM TO BE SOLVED: To provide a separator for a nonaqueous electric/electronic component, excellent in a shutdown function that is an important characteristic on a safety of a nonaqueous electric/electronic component, in particular, a secondary battery, shape stability at high temperature, and electrolyte/ion permeability while an electrolyte is held. <P>SOLUTION: The separator for a nonaqueous electric/electronic component is obtained by heat treating a thinned material in a dry state at a temperature of a melting point of a thermoplastic polymer or higher. The thinned material exists in a state where the thermoplastic polymer that has a melting point of 200°C or lower, a layer comprising particles that does not have a melting point at 300°C or lower, and a layer of a polymeric organic substance that substantially does not have a melting point at 300°C or lower are in contact. <P>COPYRIGHT: (C)2012,JPO&INPIT |
