SEPARATOR, AND DEVICE AND METHOD FOR MANUFACTURING SEPARATOR

摘要

PROBLEM TO BE SOLVED: To provide a separator capable of suppressing a nanofiber layer from being peeled to be damaged during a manufacturing process of the separator, to provide a separator manufacturing device capable of manufacturing the separator, and further to provide a separator manufacturing method capable of manufacturing the separator.

SOLUTION: A separator 1 comprises: a base material layer 10; a first nanofiber layer 20 including a first nanofiber 22; and a second nanofiber layer 30 including a second nanofiber 32 and an inorganic particle 34. The base material layer 10, the first nanofiber layer 20 and the second nanofiber layer 30 are stacked in the order of the base material layer 10, the first nanofiber layer 20 and the second nanofiber layer 30, and the base material layer 10 and the second nanofiber layer 30 are joined by the first nanofiber 22.
