[PROBLEMS] To improve the storage stability of FAD-GDH. An amino acid sequence having 70% or more identity with a specific amino acid sequence, or an amino acid sequence in which one or several amino acids are deleted, substituted or added in the amino acid sequence, Amino acid substitutions at positions corresponding to positions 196, 228, 600, 267, 276, 55, 230, 235, 239, 435, 587, 588, and / or 591 In addition, FAD-GDH has improved storage stability compared to before the substitution.
