[origin: EP3025768A1] [Object] To provide a method for storing a hollow ball easily at low cost. [Solution] A method for storing a hollow ball according to the present invention includes the steps of: (1) putting a hollow ball 4 including an outer shell and a space surrounded by the outer shell, into a housing portion 6; (2) decreasing a temperature of the hollow ball 4 to a temperature lower than a temperature of external air; and (3) storing the hollow ball in a state where the temperature of the hollow ball 4 is made lower than the temperature of the external air. Preferably, the storing method further includes the step of (4) increasing the temperature of the hollow ball 4 after the step (3). Preferably, in the step (4), the temperature of the hollow ball 4 is increased to a temperature exceeding a dew point of the external air.
