Type B silica gel as defined in IS Z 0701 has been used. This utilizes the humidity control function of B-type silica gel, and has a moisture absorption rate of 20% or less at a relative humidity of 50% (25 ° C) or less and a moisture absorption rate of 50% or more at a relative humidity of 90% (25 ° C) or more. This is because it is a silica gel having a hygroscopic property.
