1. A near-infrared curable ink composition containing composite tungsten oxide fine particles as near-infrared absorbing fine particles and uncured thermosetting resin,
wherein the composite tungsten oxide fine particles have a XRD peak top intensity ratio value of 0.13 or more based on a XRD peak intensity ratio value of 1 on plane (220) of a silicon powder standard sample 640c produced by NIST.
