    Abstract: A method of manufacturing a composite particle includes: a step of preparing a first raw material including an element selected from any of copper, molybdenum, and silver, and a second raw material including one or more types of elements selected from aluminum, titanium, zirconium, hafnium, iron, yttrium, niobium, tantalum, silicon, calcium, magnesium, tungsten, indium, tin, germanium, nickel, zinc, and molybdenum; and a thermal plasma evaporation and cooling step of introducing the prepared first and second raw materials into thermal plasma to evaporate the first raw materials, and cooling the evaporated first raw materials to generate a composite particle. The composite particle includes the second raw material, and a fine particle carried on a surface of the second raw material and generated from the first raw material having an average particle size of 0.5 nm or more and 300 nm or less.
