The oligonucleotide derivative is a repeat represented by the following general formula (wherein B represents adenine, guanine, cytosine or uracil, X represents a sulfur atom or an oxygen atom, and n represents an integer of 6 to 60). It consists of a structural unit (in the general formula, B and X are independently represented in each repeating structural unit), and X is a sulfur atom in at least one of the repeating structural units represented by the general formula. . |
