A labeled polynucleotide is subjected to hybridization with oligonucleotide probes fixed respectively to regions on a supporting material. With a first restriction enzyme, a single-stranded moiety of the labeled polynucleotide having failed to form a double strand with each probe is separated from a double strand having been formed by the labeled polynucleotide and each probe. First detection data is obtained from each region. A mismatching moiety, at which the labeled polynucleotide and a certain probe have undergone a mismatch binding, is separated with a second restriction enzyme, and second detection data is obtained from each region. The region to which the mismatch polynucleotide was bound is specified in accordance with results of a comparison between the first detection data and the second detection data.
