Abstract: A separator for an electrochemical device having a low content of secondary particles formed by aggregation of inorganic particles in the inorganic coating layer. The separator has a low content of secondary particles protruding from the separator surface to a predetermined height. Since the inorganic particles are not aggregated but are distributed homogeneously in the inorganic coating layer, the separator has uniform dispersion of pressure over the whole surface of the separator, when it is applied to a battery and pressure is generated in the battery due to the charge/discharge of the battery. Deformation of the separator is minimized. When using a porous film as a separator substrate, there is a low tendency for intensive application of pressure from the secondary particles to a local site of the separator substrate, and thus the separator substrate is less damaged and the possibility of short-circuit generation is reduced.
