PROBLEM TO BE SOLVED: To provide such a storing method of ozone and its device that ozone is produced by using inexpensive electric power such as nighttime electric power and the produced ozone is stored by using a specified high silica adsorbent having large ozone adsorptivity and a high ozone holding rate even in a system in the presence of water, and that ozone can be supplied as required. SOLUTION: In the storing method of ozone, ozone is produced by operating an ozone generating device 1 and the obtd. ozone-contg. gas is supplied to an ozone reservoir 8 packed with an ozone adsorbent containing dealuminized faujasite and/or mesoporous silicate to adsorb and store ozone at -100 deg.C adsorption temp. The ozone-contg. gas is preliminarily cooled by using an oxygen concentrated gas flowing from the ozone reservoir 8. When ozone is to be used, operation of the ozone generating device is stopped and ozone is recovered from the ozone reservoir 8 by desorption by heating, purging and desorption by heating, reduced pressure desorption, reduced pressure purging and desorption, or reduced pressure purging and desorption by heating.
