Abstract
A glass ceramics having a chemical composition of aRO.bNb.O.cSiO.dBO.eTeO.fX (where R represents Ba and/or Sr, X represents one or more oxide selected from the group consisting of TiO, ZrO, POand ZnO, a>b≧0.05, 0.60≧c≧0, 0.70≧d≧0, 0.70≧e≧0, c+d+e≧0.175, a+b+c+d+e=1.0 and 0.10≧f≧0). The ratio dielectric constant at 1 kHz εto dielectric constant at 100 kHz ε(ε/ε) is 10 or more.
