Abstract
Glass powder for a dielectric material has a nature that, when fired, diopside (CaMgSiO) and at least one of titanite (CaTi(SiO)O) and titania (TiO) are precipitated. Preferably, the glass powder has a composition including SiO, CaO, MgO, and TiOand the total content of these components is 80 mass % or more.
