  "textContent": "The present invention aims to provide a method for producing a separator for nonaqueous electrolyte electricity storage devices, the method allowing avoidance of use of a solvent that places a large load on the environment, and also allowing relatively easy control of parameters such as the porosity and the pore diameter. [0002] The present invention relates to a method for producing a separator for nonaqueous electrolyte electricity storage devices that has a thickness ranging from 10 to 50 µm, the method including the steps of: producing an epoxy resin composition containing an 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.",
