ABSTRACT:
A dielectric material comprising: a glass powder constituted of a glass comprising Si, B and an alkali metal element, the glass being amorphous in sintering at a temperature of 1,050° C. or lower; and a ceramic filler comprising at least one member of SiO2, Al2O3and 3Al2O3.2SiO2, and an alkali metal element, wherein when a total sum of Si converted into SiO2, B converted into B2O3and the alkali metal element converted into A2O, wherein A represents an alkali metal element, all of which are contained in the glass, is 100 mole %, the content of the alkali metal element converted into A2O, which is contained in the glass, is 0.5 mole % or less; and when a total sum of at least one member of SiO2, Al2O3and 3Al2O3.2SiO2, and the alkali metal element converted into A2O, all of which are contained in the ceramic filler, is 100 mole %, a content of the alkali metal element converted into A2O, which is contained in the ceramic filler, is 0.5 mole % or less.
