At present new SuperKEKB collider is under commissioning at KEK (Japan) while the Belle II detector for experiments at this collider is at the final stage of the construction. The luminosity of this collider will exceed the previous one by about 40 times, amounting to 8 1035cm-2s-1. The electromagnetic calorimeter is a very important component of the BELLE II detector. This calorimeter is described in this report.
