Abstract
Composite particles for an electrochemical device electrode including an electrode active material and a binding agent and having surfaces thereof coated with an external additive A, wherein at least one kind of the external additive A has a powder resistance of less than 10 Ω·cm, and, in the case where three axial diameters of the external additive A are a length diameter LA, a thickness tA, and a width bA, the length diameter LA is 0.1 to 5 μm and a ratio (bA/tA) between the width bA and the thickness tA is 5 or more and less than 50.
