This carbon black has a specific surface area of 150-400 m2/g. The ratio (S2/S1) of a peak area (S2) of m/z 128 peak to a peak area (S1) of m/z 57 peak, detected by a thermal desorption spectroscopy, is less than 2.00. L'invention concerne un noir de carbone qui présente une surface spécifique supérieure ou égale à １５０ｍ２／ｇ et inférieure ou égale à ４００ｍ２／ｇ, et un rapport （Ｓ２／Ｓ１） d'une surface pic （Ｓ２） d'un pic (ｍ／ｚ１２８) pour une surface pic （Ｓ１） d'un pic (ｍ／ｚ５７), détecté par analyse de gaz de désorption thermique, inférieur à 2,00. 比表面積が１５０ｍ２／ｇ以上４００ｍ２／ｇ以下であり、昇温脱離ガス分析法により検出される、ｍ／ｚ５７のピークのピーク面積（Ｓ１）に対するｍ／ｚ１２８のピークのピーク面積（Ｓ２）の比（Ｓ２／Ｓ１）が２．００未満である、カーボンブラック。
