The present invention provides a DNA fragment having a cold-inducible promoter function of yeast, which has high activity in a low temperature range, by identifying a DNA fragment, which exists in a non-translation region located upstream of the 5′-terminal side of a gene selected from the group consisting of cold-inducible genes ofSaccharomyces cerevisiae, and has a cold-inducible promoter function.
