A semiconductor light emitting device member which has excellent transparency, light resistance and heat resistance, and seals a semiconductor light emitting device without generating cracks and peeling even when used for a long period of time. The semiconductor light emitting device member wherein, (1) a solid-state Si magnetic resonance spectrum is provided with at least one peak selected from (i) a peak wherein a peak top position is in a region having a chemical shift of-40ppm or more but not more than 0ppm and a peak half value width is 0. 3ppm or more but not more than 3.0ppm, and (ii) a peak selected from a group composed of peaks wherein peak top positions are in a region having a chemical shift of-80ppm or more but less than-40ppm and a peak half value width is 0.3ppm or more but not more than 5.0ppm, (2) a silicon content rate is 20 wt.% or more, and (3) a silanol content is 0.1 wt.% or more but not more than 10 wt.%, is used. |
