PROBLEM TO BE SOLVED: To obtain conductive fine particles having excellent heat resistance, excellent dispersibility in a resin by reducing specific gravity, and cost reduced. SOLUTION: Polymer fine particles comprising a polymer (a) having a glass transition temperature of 100 ° C. or more and 300 ° C. or less and at least one selected from the group consisting of a polyurethane resin, a polyester resin, a polyamide resin, and an epoxy resin. A) is coated with a conductive metal (B), particularly silver, so that the average coating thickness is 0.01 to 10 μm or less, and the specific gravity is 1 or more and 3 or less. Fine particles (C) are used. [Selection figure] None. |
