  "textContent": "A method for producing a thermoplastic resin micro-porous film wherein a thermoplastic resin and a solvent (A) are melted and kneaded together to prepare a solution, the solution is extruded and cooled to prepare a formed product in a gel state, and the residual solvent (A) is removed from the formed product, characterized in that in the step of removing the solvent (A) use is made of a non-aqueous solvent (B) which is compatible with the solvent (A) and not compatible with the thermoplastic resin, and has a boiling point of 100 DEG or higher and a flashing point of 0 DEG or higher. The use of the non-aqueous solvent (B) provides a production method which allows the removal of a solvent with good efficiency and also with the reduction of a fear of environmental pollution and catching fire.",
