PROBLEM TO BE SOLVED: To provide a glass composition of good and stable quality that is suitably used as a glass filler to be blended with a polycarbonate resin and can reduce a load of glass manufacturing equipment, and to provide uses of the glass composition. SOLUTION: The glass composition contains as essential components silicon dioxide (SiO<SB>2</SB>), aluminum oxide (Al<SB>2</SB>O<SB>3</SB>), magnesium oxide (MgO), calcium oxide (CaO), strontium oxide (SrO) and zirconium oxide (ZrO<SB>2</SB>). The contents are set as follows: 50-60 mass% of silicon dioxide, 5-15 mass% of aluminum oxide, 1-10 mass% of magnesium oxide, 10-25 mass% of calcium oxide, 8-25 mass% of strontium oxide and 1-7 mass% of zirconium oxide.
