PROBLEM TO BE SOLVED: To provide a glass ceramic composition which can be fired at a low temperature and has an extremely low dielectric constant and sufficient deflection strength, and to provide a coil electronic component using the same.SOLUTION: The glass ceramic composition has a main component comprising first glass, second glass, AlO, and SiO. The first glass is SiO-KO-BO-based glass. The second glass is MO-SiO-AlO-BO-based glass (M is an alkaline earth metal) and/or CaO-SiO-AlO-ZnO-ZrO-BO-based glass. When the total amount of the main component is 100 wt.%, the main component contains 12-30 wt.% of the second glass, 40-56 wt.% in total of the first glass and the second glass, and 7-18 wt.% of AlO.SELECTED DRAWING: None |
