Organic el light-emitting device and illumination device

An organic EL light-emitting device, comprising:

• a first substrate;
• an organic EL element disposed on the first substrate;
• a second substrate disposed so as to face the first substrate with the organic EL element in-between;
• and
• a sealing member disposed between the first substrate and the second substrate so as to surround the organic EL element, and
• further comprising a protection layer, a hygroscopic member, a contact prevention member, and a moisture permeable member which are disposed within a space enclosed by the first substrate, the second substrate and the sealing member,
• the protection layer for covering the organic EL element,
• the hygroscopic member for covering the protection layer and absorbing moisture within the space,
• the contact prevention member for preventing contact between the organic EL element and the second substrate, and
• the moisture permeable member being in contact with the hygroscopic member and the contact prevention member and allowing moisture within the space to permeate.
