The invention provides a novel glass filler with a low dielectric constant. Provided is a glass filler comprising a glass composition comprising, in wt%, 95 < = SiO2 < = 99.5, 0 < = B2O3 < = 2, 0.01 < = Al2O3 < = 4, 0 < = R2O < = 4, 0.01 < = RO < = 4, and 0 < = TiO2 < = 4. Wherein RO is at least one selected from the group consisting of MgO, CaO, SrO, and ZnO, and R2O is at least one selected from the group consisting of Li2O, Na2O, and K2O. The glass filler may have a dielectric constant of less than 4 at 1 GHz. 本发明提供一种介电常数低的新型玻璃填料。提供的玻璃填料包含玻璃组合物，玻璃组合物以重量％计包含95≤SiO2≤99.5、0≤B2O3≤2、0.01≤Al2O3≤4、0≤R2O≤4、0.01≤RO≤4、0≤TiO2≤4。其中，RO为选自MgO、CaO、SrO及ZnO中的至少一种，R2O为选自Li2O、Na2O及K2O中的至少一种。该玻璃填料在1GHz下可以具有小于4的介电常数。
