Zusammenfassung:	To provide crystallized glass with high temperature stability in high frequency regions, a dielectric material and a high-frequency dielectric device.SOLUTION: Crystallized glass comprises, in mol%, 6.3% to 25% of SiO2, 0%-20% of Al2O3, 10% to 70% of TiO2, more than 0% to 15% of ZrO2, 5% to 35% of BaO, and 25% or more of SiO2+Al2O3. The crystallized glass is substantially free of rare earth oxide and comprises Ba4Ti12O27 as its primary deposited crystal.SELECTED DRAWING: None 【課題】高周波数領域において温度安定性が高い結晶化ガラス、誘電体材料及び高周波誘電体デバイスを提供する。【解決手段】モル％で、ＳｉＯ２６．３％～２５％、Ａｌ２Ｏ３０％～２０％、ＴｉＯ２１０％～７０％、ＺｒＯ２０％超～１５％、ＢａＯ５％～３５％、ＳｉＯ２＋Ａｌ２Ｏ３≦２５％を含有し、希土類酸化物を実質的に含有せず、析出主結晶としてＢａ４Ｔｉ１２Ｏ２７を含む、結晶化ガラス。【選択図】なし
