The present invention is intended to provide a sealing material for a light emitting device, which is able achieve both the adhesiveness and the crack resistance, have the high sulfurization resistance and the wet heat resistance, and seal the light emitting element. The sealing material for a light emitting device for sealing a light emitting element is characterized in that in a solid Si-nuclear magnetic resonance spectrum, a peak has a peak top in a chemical shift within a range of −120 ppm or more and −90 ppm or less, and a half width of 5 ppm or more and 12 ppm or less; in the solid Si-nuclear magnetic resonance spectrum, a peak has a peak top in a chemical shift within a range of −80 ppm or more and −40 ppm or less, and a half width of 5 ppm or more and 12 ppm or less; and a silanol content ratio is 11% by weight or more and 30% by weight or less. |
