  "textContent": "The present invention provides a method for producing a separator for nonaqueous electrolyte electricity storage devices. The method allows: avoidance of use of a solvent that places a large load on the environment; relatively easy control of parameters such as the porosity and the pore diameter; and a relatively high strength of a resultant separator for nonaqueous electrolyte electricity storage devices. The present invention relates to a method for producing a separator for nonaqueous electrolyte electricity storage devices that has a thickness ranging from 5 to 50 µm. The method includes the steps of: preparing an epoxy resin composition containing a glycidylamine-type epoxy resin, a curing agent, and a porogen; forming a cured product of the epoxy resin composition into a sheet shape or curing a sheet-shaped formed body of the epoxy resin composition, so as to obtain an epoxy resin sheet; and removing the porogen from the epoxy resin sheet by means of a halogen-free solvent.",
