Abstract
Glass powder for a dielectric material has a nature that, when fired, diopside (CaMgSi2O6) and at least one of titanite (CaTi(SiO4)O) and titania (TiO2) are precipitated. Preferably, the glass powder has a composition including SiO2, CaO, MgO, and TiO2 and the total content of these components is 80 mass % or more. Preferably, the glass powder comprises, by mass percent, 35-65% SiO2, 10-30% CaO, 10-20% MgO, and 12-30% TiO2.
