摘要：
The object of an exemplary embodiment of the invention is to provide a separator for an electric storage device which has small thermal shrinkage under high-temperature environment, and in which the increase of the battery temperature can be suppressed. An exemplary embodiment of the invention is a separator for an electric storage device, which comprises a cellulose derivative represented by a prescribed formula. The separator for an electric storage device can be obtained, for example, by treating a cellulose separator containing cellulose with a phosphate or a phosphite.
