[Problem] To provide a means that can minimize an increase in the internal resistance of a non-aqueous electrolyte secondary battery. [Solution] A core-shell-type electrode material is used as an electrode active material layer of a non-aqueous electrolyte secondary battery, said core-shell-type electrode material comprising: a core part that includes an electrode active material; and a shell part in which an electroconductive material is included in a base material made of a gel-forming polymer having a tensile elongation at break of 10% or greater in a gel state.
