Beschreibung
Zusammenfassung:	The composite secondary particles of the present invention comprise primary particles of fluororesin and carbon nanotubes, the composite secondary particles composed of primary particles of fluororesin aggregated and carbon nanotubes existing between the primary particles of fluororesin, wherein the average length of the carbon nanotubes is 50 to 1000 [mu]m, the average particle diameter of the primary particles of the fluororesin is 1 to 300 [mu]m, and the average particle diameter of the composite secondary particles is 150 [mu]m or more, the average particle size of the composite secondary particles is larger than the average particle size of the primary particles, and the composite secondary particles contain 0.01 to 2.0 mass% of carbon nanotubes.
