To analyze the concentration of nano diamond particles in a composite plating solution quickly and accurately in a simple manner and control the composite plating solution appropriately.SOLUTION: A method of analyzing the concentration of nano diamond particles in a composite plating solution includes a step of measuring the absorbance of the composite plating solution containing the nano diamond particles and determining the concentration of the nano diamond particles on the basis of the measured value of the absorbance. The absorbance is measured with a wavelength selected from the range of 250 to 630 nm.SELECTED DRAWING: None 【課題】複合めっき液中のナノダイヤモンド粒子の濃度を簡易な方法で迅速かつ的確に分析し、複合めっき液を適切に管理する。【解決手段】ナノダイヤモンド粒子を含む複合めっき液の吸光度を測定し、吸光度の測定値に基づきナノダイヤモンド粒子の濃度を求める工程を含み、前記吸光度は２５０～６３０ｎｍの範囲から選択される波長で測定される、複合めっき液中のナノダイヤモンド粒子濃度の分析方法。【選択図】なし
