The present invention discloses a desiccant composition, which includes a water-catching component and a binder. The water-catching component includes strontium oxide particles and may further include calcium oxide particles. The binder includes a polymerizable component. The ratio of the amount of strontium oxide particles to the total amount of strontium oxide particles and calcium oxide particles is less than 50% by mass.
