Abstract
Disclosed are a separator having an electrode adhesive layer and an electrochemical device including the same. The electrode adhesive layer includes organic particles and an acrylic resin binder. Preferably, the acrylic resin binder is present in an amount of 30 wt % or more, so that a film-shaped electrode adhesive layer can be formed even when the organic particles have a particle diameter smaller than that of the pores of the underlying substrate or voids of the underlying porous coating layer.
