The present invention provides a negative electrode for a secondary battery capable of realizing a secondary battery with high reliability and excellent cycle characteristics, and a method for manufacturing the same. The present invention provides a negative electrode for a secondary battery and a manufacturing method thereof. The negative electrode for a secondary battery has a current collector, a negative electrode active material layer, and a porous film, and the negative electrode active material layer contains a negative electrode active material and a particulate negative electrode. Using a polymer, the porous membrane contains non-conductive particles and non-particle-shaped cross-linked polymers for porous membranes, and the non-conductive particles contain more than 50% by weight of (meth)acrylate polymerized Particles of polymers that form structural units and have a softening initiation temperature or decomposition temperature of 175°C or higher. |
