To produce an aseptically stored blood for blood transfusion free from the contamination of a pathogenic microbe and an infusion solution containing the blood.

The present invention provides a production method for an aseptically stored blood for blood transfusion characteristic in that pathogenic viruses and bacteria which may exist in a stored blood are killed by treating the collected and stored blood by super electrolysis. It also provides a method for producing an infusion solution containing the stored blood characteristic in that the aseptically stored blood for flood transfusion treated by super electrolysis is mixed with an infusion solution (physiological saline) treated by super electrolysis for sterilization.
