The task is to provide SOLUTION: This is a solid humidity control material using pearlite particles, at least the surface of which is composed of pearlite modified to have a density of 0.3 to 0.5 g / cm 3 mainly composed of an alkali metal polyaluminosilicate. The solid humidity conditioner is a solution. |
