A sequential pattern detecting apparatus includes a first combining unit configured to combine a plurality of characteristic event sets detected from sequential data containing elements which comprise a plurality of events and which are arranged in sequential order, to generate a characteristic primary sequential pattern with a sequence size of "1", a second combining unit configured to combine a plurality of characteristic ith-length (i=1, 2, . . . ) sequential patterns with a sequence size of "i" to generate a candidate (i+1)th-length sequential pattern, a checking unit configured to check validity of the candidate (i+1)th-length sequential pattern on the basis of the attributes to detect valid (i+1)th-length sequential patterns, and a detecting unit configured to detect a characteristic (i+1)th-length sequential pattern from the valid (i+1)th-length sequential patterns with reference to the sequential data.
