Beschreibung
Zusammenfassung:	The present invention relates to a crystallized glass including a crystalline phase consisting of Ba-Si-O, in which the crystallized glass includes Li, and crystallinity of Li-based crystals contained in the crystalline phase is 20% or lower as represented by weight %, a high-frequency substrate including the crystallized glass, and a manufacturing method for a crystallized glass including a crystalline phase consisting of Ba-Si-O, the method including: obtaining an amorphous glass by melt-shaping a material containing BaO and SiO2; and crystallizing the amorphous glass by holding the amorphous glass at a treatment temperature of 600° C. or higher and lower than 1,000° C.
