The present invention is intended to provide a sealing material for a li ght emitting device, which is able achieve both the adhesiveness and th e crack resistance, have the high sulfurization resistance and the wet h eat resistance, and seal the light emitting element. The sealing material for a light emitting device for sealing a light emitting element is char acterized 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 1 2 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 an d 30% by weight or less. |
