First claim
Opening claim text (preview).
1 . ITO particles satisfying a relationship expressed in Expression (1) given below: 16× S/P 2≤0.330 (1) wherein S indicates a particle area in a TEM photographed image, and P indicates a perimeter of the particle. 2 . The ITO particles according to claim 1 , wherein a molar ratio of a content amount of Sn to a content amount of In (Sn/In) falls within a range from 3.5 to 24. 3 . The ITO particles according to claim 1 , wherein an aligned crystal orientation is provided inside particles. 4 . Dispersion comprising the ITO particles according to claim 1 , dispersed in a solvent. 5 . The dispersion according to claim 4 , wherein the solvent comprises water. 6 . The dispersion according to claim 4 , wherein the dispersion is substantially prevented from comprising a surfactant. 7 . The dispersion according to claim 4 , wherein a ratio of a volume of the ITO particles to a volume of the solvent is 40% or less. 8 . A production method of an ITO film, comprising: forming the dispersion according to claim 4 into mist; bringing the misted dispersion, into contact with a base plate; and drying the dispersion on the base plate after the contact.
