To provide a resin composition which can enhance all of tensile strength, bending strength and impact resistance of an injection molding.SOLUTION: The resin composition contains an aromatic polysulfone and an organic filler. The organic filler comprises an aromatic polyester particulate. The content of the aromatic polyester particulate is 1-50 pts.mass based on 100 pts.mass of the aromatic polysulfone. The median size D50 of the organic filler is 70 μm or less. The ratio D90/D10 of the particle size of the organic filler is 6.0 or less.SELECTED DRAWING: None 【課題】射出成型品の引張強度、曲げ強度、耐衝撃性をいずれも高められる樹脂組成物の提供。【解決手段】芳香族ポリスルホンと有機フィラーとを含有する樹脂組成物において、有機フィラーが、芳香族ポリエステル粒子を含み、芳香族ポリエステル粒子の含有量が、芳香族ポリスルホン１００質量部に対して１〜５０質量部であり、有機フィラーのメジアン径Ｄ５０が、７０μｍ以下であり、有機フィラーの粒径の比Ｄ９０／Ｄ１０が、６．０以下である、樹脂組成物。【選択図】なし
