| description | To provide a production method of composite tungsten oxide particles capable of producing composite tungsten oxide particles having a target composition.SOLUTION: A production method of composite tungsten oxide particles represented by general formula: MxWyOz, having a particle size of 300 nm or less includes a raw material preparation step for preparing a raw material containing the M element and a tungsten element and a heat treatment step for heat-treating the raw material at a temperature of 500°C or higher. In the raw material preparation step, the raw material is prepared so that the ratio a/b of an amount "a" of the M element and an amount b of the tungsten element contained in the raw material is larger than the ratio x/y of an amount x of the M element and an amount y of the tungsten element in a target composition of the composite tungsten oxide particles by 2.5% or more and 15% or less.SELECTED DRAWING: Figure 1
