description The present application provides a separator, a secondary battery, a battery module, a battery pack and an electrical apparatus. The separator sequentially includes a first region, a main region and a second region in a first direction. At least one surface of the first region and/or at least one surface of the second region is provided with a fluorescent coating. The fluorescent coating is used to identify whether the separator is folded or not. The separator of the present application is allowed to be identified in time after being folded, and the folded separator is prevented from being made into a lithium-ion battery, which is conductive to increasing yield of the lithium-ion battery.
