To provide a determination method of paper money or the like and a determining apparatus of the paper money or the like for drastically improving the determination precision of the paper money or the like.

A detection data table 13 by detection data 12 is created. The difference between the detection data value of the detection part of the detection data table 13 and the detection data value of the adjacent detection part of the detection part is calculated by differential processing and a feature differential data value is extracted. A feature difference data table 15 by the feature difference data value is created. A criterion feature difference data table registration section 18 for registering a criterion feature difference data table 17 of a reference true ticket paper money, such as a true ticket paper money, created by the similar formation stage as that of the feature difference data table 15 in advance, the feature difference data table 15, and the criterion feature difference data table 17 are compared for determination.
