PROBLEM TO BE SOLVED: To provide a function database generation method and a function database generation device generating a function database the optimum number of classifications of which is quantitatively determined by using a numerical index when classifying a function curve into various kinds of clusters. SOLUTION: The function database generation device A is provided, inside a computation processing part 3, with: a function cluster result acquisition part 31 for acquiring the function cluster analysis result of the plurality of function curves; a classification number determination part 32 for calculating an index indicating the degree of unity for each cluster of the function cluster analysis result and determining the number of the clusters for which the change of the index to the change of the number of clusters is a prescribed value or less as the number of classifications; and a database output part 34 for turning the function curves into a database by the determined number of classifications and outputting it.
