Abstract
Composite particles for an electrochemical device electrode containing an electrode active material, a conductive material, and a binder, wherein primary particles of the composite particles have a volume average particle size of 1 to 500 μm and, when a relative particle amount of the primary particles having a particle size of a fine range near a mode radius Rof the primary particles in the particle size distribution of the primary particles of the composite particles found by the volume standard is ρand a relative particle amount of secondary particles having a particle size of the fine range in the particle size distribution of the secondary particles of the composite particles found by the volume standard in measurement at 23° C. is ρis 0.03 to 0.60.
