PROBLEM TO BE SOLVED: To provide a biological information authentication device which especially creates one registered biological information feature point list by combining a plurality of biological information feature point lists with high precision. SOLUTION: The biological information authentication device which performs personal authentication of the user by collating registered biological information with inputted biological information, is provided with a biological information input means (110) for inputting a biological information image, a feature extraction means (150) for extracting a plurality of feature points from the inputted biological information image so as to generate biological information features constituted of information about the feature points, a storage means (120) for storing a plurality of biological information features, a similarity decision means for calculating similarity by collating the plurality of biological information features and deciding whether or not the biological information features are similar, a feature combination means (160) for combining the stored biological information features and generating the combined biological information features when the similarity decision means decides that the biological information features are similar and a feature registration means (170) for setting the combined biological information features in the registered biological information.
