Abstract: An object of the present invention is to provide composite particles for an electrochemical device electrode capable of preparing an electrode having high thickness precision at a low basis weight, an electrochemical device electrode and an electrochemical device that use the composite particles for an electrochemical device electrode, and to provide a method for manufacturing the composite particles for an electrochemical device electrode, and a method for manufacturing the electrochemical device electrode.The present invention relates to composite particles for an electrochemical device electrode that are obtained by spray-drying a slurry containing an electrode active material and a binder resin, in which particles of 40 μm or less are 50% or less of an entire amount in a number-based particle size distribution obtained by particle size measurement using a laser light diffraction method and the cumulative 95% size (D95 size) is 300 μm or less in a volume-based particle size distribution.
