Disclosed is a capillary electrophoresis method for simultaneously electrophoresing an unknown sample and an internal standard material, determining an earliest peak as a peak derived from the internal standard material, and identifying the unknown sample on the basis of the internal standard substance-derived peak. The internal standard substance consists of a fluorescent substance or a salt thereof which has a positive or negative net charge of 2 or more in an electrolyte solution used for capillary electrophoresis. An earliest one of detected peaks is determined as a peak derived from the internal standard substance, and the remaining peaks are identified on the basis of the internal standard substance-derived peak.
