PROBLEM TO BE SOLVED: To provide a novel 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 to hold a phosphor.SOLUTION: In the semiconductor light-emitting device member, (1) a solid-state Si magnetic resonance spectrum is provided with at least one peak selected from (i) a peak where a peak top position is in a region having a chemical shift of -40 ppm or more but not more than 0 ppm and a peak half value width is 0.5 ppm or more but not more than 3.0 ppm, and (ii) a peak selected from a group composed of peaks where peak top positions are in a region having a chemical shift of -80 ppm or more but less than -40 ppm and a peak half value width is 1.0 ppm or more but not more than 5.0 ppm; (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.%. |
