Abstract
Disclosed are a separator and an electrochemical device including the same. The separator includes: a porous polymer substrate having a plurality of pores; a separator base including a porous coating layer formed on at least one surface of the porous polymer substrate, and including a plurality of inorganic particles and a binder polymer disposed partially or totally on the surface of the inorganic particles to connect and fix the inorganic particles with each other; and an adhesive porous layer formed on at least one surface of the separator base and including an adhesive resin which shows adhesive property through heating at a temperature lower than the melting point of the porous polymer substrate, wherein the adhesive porous layer is provided with a porous structure formed by phase separation caused by the evaporation rate of a solvent and that of a non-solvent, when applying and drying a coating composition including the adhesive resin, the solvent and the non-solvent on at least one surface of the separator base.
