Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a conductive particle whose dispersibility into a resin is improved.SOLUTION: In a conductive particle in which at least the surface area includes tin oxide, the value of BET/BETas a ratio between BET specific surface area BET(m/g) and BET(m/g) measured using water is controlled to 0.2 to 0.7. It is suitable that the BETis controlled to 3.0 to 35.0 m/g. Further, the BET specific surface area measured using nitrogen BETis suitably controlled to 15 to 50 m/g. 【課題】樹脂中への分散性が向上した導電性粒子を提供すること。【解決手段】少なくとも表面域が酸化スズを含む導電性粒子において、水を用いて測定されたＢＥＴ比表面積ＢＥＴＨ２Ｏ（ｍ２／ｇ）とＢＥＴＮ２（ｍ２／ｇ）との比であるＢＥＴＨ２Ｏ／ＢＥＴＮ２の値を０．２以上０．７以下とした。ＢＥＴＨ２Ｏが３．０ｍ２／ｇ以上３５．０ｍ２／ｇ以下であることが好適である。また、窒素を用いて測定されたＢＥＴ比表面積ＢＥＴＮ２を１５ｍ２／ｇ以上５０ｍ２／ｇ以下とすることが好適である。【選択図】図１
