[PROBLEMS] To be superior to conventional sensing technology in terms of measurement accuracy, glucose reaction specificity and storage stability as an electrode sensor, which are particularly useful in self blood glucose measurement, and under a wider temperature range. However, the present invention provides a glucose dehydrogenase, a glucose measurement method using the glucose dehydrogenase, and an enzyme composition that can perform stable measurement. When the activity value at 50 ° C. is 100%, the activity value at 20 ° C. is 30% or more, preferably the activity value at 10 ° C. is 15% or more, more preferably the activity value at 5 ° C. is 10%. More preferably, the activity value at 60 ° C. is 70% or more, and a glucose dehydrogenase and a method for electrochemical measurement of glucose using the glucose dehydrogenase.
