Abstract

See full text

A glass powder of the present invention is a glass powder, which is formed of alkali borosilicate glass, wherein the glass powder includes 0.1 mol % to 1.0 mol %, provided that 1.0 mol % is excluded, of Li2O+Na2O+K2O in a glass composition, has a molar ratio Li2O/(Li2O+Na2O+K2O) of from 0.35 to 0.65, a molar ratio Na2O/(Li2O+Na2O+K2O) of from 0.25 to 0.55, and a molar ratio K2O/(Li2O+Na2O+K2O) of from 0.025 to 0.20, and has a specific dielectric constant at 25° C. and 16 GHz of from 3.5 to 4.0 and a dielectric dissipation factor at 25° C. and 16 GHz of 0.0020 or less.
