  "textContent": "This application relates to a separator for a lithium secondary battery, a method for manufacturing a separator for a lithium secondary battery, and a lithium secondary battery including same. The separator includes a porous substrate, a heat resistant layer positioned on at least one surface of the porous substrate and including inorganic particles, and a first adhesive layer positioned on the heat resistant layer and including a first organic polymer. The heat resistant layer includes the inorganic particles of 90 wt % to 99 wt % on the basis of total weight, the thickness of the heat resistant layer is 3.5 μm to 7 μm, and the thickness of the first adhesive layer is 0.5 μm to 3.0 μm.",
