Disclosed is a composition for forming a porous insulating layer for suppressing an increase in the layer thickness of an active material layer of an electrode, a method for manufacturing an electrodefor a non-aqueous electrolyte rechargeable battery, an electrode for a non-aqueous electrolyte rechargeable battery manufactured according to the method, and a non-aqueous electrolyte rechargeable battery including the electrode. The composition for forming a porous insulating layer according to the present disclosure is a composition for forming a porous insulating layer on an active material layer provided on a main surface of a current collector. The active material layer includes at least an active material capable of electrochemically intercalating and deintercalating lithium ions and anactive material layer binder. A composition for forming a porous insulating layer includes a solvent including an organic solvent and insulating inorganic particles. The distance between the active material layer binder and t
