The present disclosure provides a novel glass filler which has low permittivity and is suitable for mass production. A glass filler provided herein includes a glass composition which contains, by wt%, for example, 40 <= SiO2 <= 60, 25 <= B2O3 <= 45, 0<Al2O3<= 18, 0<R2O <= 5, 0 <= RO <= 12, and in which at least one among i) SiO2+B2O3 >= 80, SiO2+B2O3+Al2O3 <= 99.9, and ii) SiO2+B2O3 >= 78, SiO2+B2O3+Al2O3 <= 99.9, 0<RO<10 is satisfied. Another glass filler provided herein includes a glass composition that contains SiO2, B2O3, Al2O3, and R2O, which respectively have the same contents as above, and 3<RO<8, and in which SiO2+B2O3 >= 75 and SiO2+B2O3+Al2O3<97 are satisfied. However, R2O equals Li2O+Na2O+K2O, and RO equals MgO+CaO+SrO. 本公开提供介电常数低、适合于量产的新的玻璃填料。所提供的玻璃填料包含玻璃组合物，该玻璃组合物中，以重量％表示，例如包含40≤SiO2≤60、25≤B2O3≤45、0＜Al2O3≤18、0＜R2O≤5、0≤RO≤12，i)和ii)中的至少一者成立：i)SiO2+B2O3≥80、SiO2+B2O3+Al2O3≤99.9；ii)SiO2+B2O3≥78、SiO2+B2O3+Al2O3≤99.9、0＜RO＜10。所提供的其他玻璃填料包含玻璃组合物，该玻璃组合物包含含有率与上述范围相同的SiO2、B2O3、Al2O3、R2O以及3＜RO＜8，SiO2+B2O3≥75、S
