Abstract

This invention relates to a PET nonwoven fabric for a separator for a secondary battery, and to a separator for a secondary battery including the same. The PET nonwoven fabric includes first fibers composed of PET having a melting temperature of 240A?C or more and second fibers composed of PET having a melting temperature of 180 ~ 220A?C, respective fibers having two types of fibers having different diameters, and has a fine pore size and uniform pore distribution and exhibits superior surface properties, low surface defects, high mechanical strength and excellent mass production. Even when the temperature of a battery is increased to 200A? c or more, the PET nonwoven fabric has heat resistance which prevents thermal runaway and does not generate melting and shrinking.
