摘要

PPROBLEM TO BE SOLVED: To provide a composite electrolyte film in which a polymer base material by a laser ablation processing is perforated at a higher aspect ratio with a smaller pore diameter than that in a prior art, to thereby simply conduct precisely boring processing as compared with the prior art, and which particularly utilizes many precise through holes opened at a polymer film and a polymer sheet. PSOLUTION: The manufacturing process of a polymer electrolyte film comprises a step of irradiating the polymer film or the polymer sheet with a laser to generate a plurality of through pores in the thickness direction of this polymer film or the polymer sheet, a step of shrinking the diameter of a pore perforated at the polymer film or the polymer sheet, and a step of filling an electrolyte formation monomer in the fine through hole and then polymerizing the electrolyte formation monomer to a composite polymer electrolyte film.
