Zusammenfassung:	The present disclosure relates to a crosslinked polyolefin separator which has gels with a longer side length of 50 µm or more in a number ranging from 0 to 3 per 1 m2of the separator, and shows a standard deviation of absorbance ratio between the center of the separator and the side thereof ranging from 0.01 to 0.5. The present disclosure also relates to a method for manufacturing the crosslinked polyolefin separator. According to an embodiment, the method includes the steps of: (S1) preparing a polyolefin porous membrane; and (S2) applying a coating solution containing an initiator and alkoxy group-containing vinylsilane onto at least one surface of the porous membrane. According to the method, the coating solution can permeate even to the inside of exposed pores. Thus, it is possible to provide a crosslinked polyolefin separator in which silane crosslinking occurs uniformly even inside of the pores.
