Zusammenfassung:	A factor analysis device includes: a grouping unit 501 to divide a plurality of time-series of explanation that are time-series of data of a plurality of explanatory variables corresponding to a time-series of objective that is time-series of data of one objective variable, into one or more groups such that time-series of explanation having a similarity relationship belong to a same group; a representative time-series extraction unit 502 to extract a representative time-series of explanation from each group; and an analysis unit 503 to analyze an extracted time-series of explanation to identify a time-series of explanation considered to be an influence factor for the time-series of objective.
