Beschreibung
Zusammenfassung:	A moisture absorbent for an organic EL element having hydrophobicity and no reduction in moisture absorption speed, and a method for producing the moisture absorbent are provided. The moisture absorbent for an organic EL element includes, as a main component, calcium oxide particles each having an alkoxide layer on the surface thereof. Furthermore, the method for producing a moisture absorbent for an organic EL element includes dry-pulverizing calcium oxide in the presence of an alcohol, and thereafter dry-treating the pulverized calcium oxide.
