Abstract
A general-purpose composite tungsten oxide ultrafine particles capable of producing a dispersion liquid with high productivity while having properties such as good visible light transmittance and shielding light in a near-infrared region, and a composite tungsten oxide ultrafine particle dispersion liquid using the same, wherein a value of an XRD peak top intensity ratio of the composite tungsten oxide ultrafine particles is 0.13 or more when the XRD peak intensity is set to 1, with plane of a silicon powder standard sample (640 c produced by NIST) as a reference.
