Abstract (in Japanese) (See Japanese page) 
(in English) A Binary Decision Diagram (BDD) gives efficient boolean function manipulations. The memory efficiency of BDDs depends on the number of their nodes. We can reduce the number of nodes of BDDs by adding attributed edges: nodes are shared efficiently since the number of the same sub-graphs increases when attributed edges are used. Sequence Binary Decision Diagram (SeqBDD) is a data structure that represents a set of strings. SeqBDDs are different from BDDs with respect to the variable ordering and the construction rules. Therefore, there may be another approach to share nodes of SeqBDDs. In this paper, we propose a new technique for sharing nodes of SeqBDDs with attributed edges. We prove that there exists only one canonical SeqBDD with attributed edges corresponding to one set of strings. This property is the same in the case of SeqBDDs. Therefore, our proposed data structures give efficient sets of manipulations as well as SeqBDDs.
