Disclosed is a glycogen having a weight average molecular weight of 1,000,000 Da or more. A glycogen having a weight average molecular weight of 1,000,000 Da or more is provided. When the product obtained by allowing pullulanase of 50 U / g substrate to act on this glycogen at 60 ° C. for 30 minutes, the weight average molecular weight when analyzed by the MALLS method is 500,000 Da or more, and 300 U / g in this glycogen The weight average molecular weight when the product obtained when g substrate α-amylase is allowed to act at 37 ° C. for 30 minutes is analyzed by the MALLS method is 500,000 Da or more.
