Zusammenfassung:	To provide a method of producing fluorocarbon resin powders capable of finely powdering in a state in which characteristics such as abrasion resistance are kept.SOLUTION: A method of producing fluorocarbon resin powders includes a step (S3) of forming fine powders having a smaller average particle diameter than fluorocarbon resin coarse powders that are to be pulverized by a wet mortar type method. In the step (S3), the coarse powders are dispersed in water containing a dispersion assisting agent.SELECTED DRAWING: Figure 1 【課題】耐摩耗性等の特性を保った状態で微粉化可能なフッ素樹脂粉体の製造方法を提供する。【解決手段】フッ素樹脂粉体の製造方法は、湿式の臼式法によりフッ素樹脂の粗粉を粉砕して、前記粗粉よりも平均粒径の小さい微粉を生成する工程（Ｓ３）を含み、前記（Ｓ３）工程では、前記粗粉が分散助剤を含有する水に分散している。【選択図】図１
