Beschreibung
Zusammenfassung:	The purpose of the present invention is to provide an electrode active material layer exhibiting excellent mechanical strength. This electrode material for a non-aqueous electrolyte secondary battery includes at least an electrode active material, a carbon-based conductive auxiliary agent, and a binder. The carbon-based conductive auxiliary agent has a linear structure, and includes ultra-fine fibrous carbon having an average fibre diameter of more than 200 nm but not more than 900 nm. The electrode material configures an electrode active material layer in which the maximum tensile strength (σM) in a planar direction and the tensile strength (σT) in an in-plane direction orthogonal to the maximum tensile strength (σM) satisfy relational expression (a), namely σM/σT≤1.6.
