摘要： [Summary] One embodiment of the present invention provides a powder. The powder includes ZnO, Al2O3, and SiO2 as components. In a ternary phase diagram of the ZnO, the Al2O3, and the SiO2, the powder has a composition included in a rectangular area having as the four corners thereof (ZnO (mol %), Al2O3 (mol %), SiO2 (mol %))=(24, 13, 63), (19, 18, 63), (37, 12, 51), (32, 17, 51). The ratio (S001/S101) of the area S001 of a peak appearing in the range of 15°≤2θ≤17° and the area S101 of a peak appearing in the range of 24°≤2θ≤27° in an X-ray diffraction pattern is 0.001-0.07.
