摘要 A method is provided for manufacturing an electrode that has a porous inorganic layer on the surface of an active material layer and is suitable for constructing a nonaqueous secondary battery with excellent input-output performance. In this manufacturing method, an electrode perform, which has an active material layer (344) consisting primarily of active material particles (42) and supported on a collector (342), is prepared. The water concentration of at least the surface (344a) of the active material layer (344) is adjusted to 100 ppm to 500 ppm. A slurry (S) containing inorganic particles (44), a binder and an organic solvent is coated on the surface (344a) of the active material layer with the water concentration thus adjusted, to form a porous inorganic layer.
