Beschreibung
Zusammenfassung:	The present invention provides a method of producing a carbon material for lithium ion secondary battery negative electrode, the carbon material containing a plurality of carbon particles, the method comprising the steps of: preparing a resin dispersion material containing a dispersion medium and a plurality of resin particles which are substantially insoluble in the dispersion medium; ejecting a plurality of liquid droplets of the resin dispersion material using a liquid droplet ejecting method, the liquid droplets each containing the dispersion medium and at least one of the resin particles; and heat-treating the plurality of liquid droplets so that the resin particle contained in each liquid droplet is carbonized while removing the dispersion medium to thereby obtain at least one of the carbon particles from each liquid droplet.
