To provide a polyphenylene sulfide resin composition that does not significantly impair the excellent mechanical strength that a polyphenylene sulfide resin originally has, as well as exhibits excellent low die contamination and tracking resistance and provide a molding thereof.SOLUTION: A polyphenylene sulfide resin composition contains, relative to 100 pts.wt. of (A) a polyphenylene sulfide resin, (B) 5-50 pts.wt. of a polyamide resin represented by the following structural formula, having a viscosity number of 150 ml/g or more measured in accordance with ISO 307(2007), (C) an elastomer of 3-70 pts.wt., and (D) magnesium hydroxide of 50-250 pts.wt. (In the structural formula, a is a natural number of 5 or more, b is a natural number of 7 or more).SELECTED DRAWING: None 【課題】ポリフェニレンサルファイド樹脂が本来有する優れた機械的強度を大きく損なうことなく、低金型汚れ性、耐トラッキング性にも優れたポリフェニレンサルファイド樹脂組成物とその成形品を提供する。【解決手段】（Ａ）ポリフェニレンサルファイド樹脂１００重量部に対して、（Ｂ）ＩＳＯ ３０７（２００７）に準拠して測定した粘度数が１５０ｍｌ／ｇ以上である下記構造式で表されるポリアミド樹脂を５〜５０重量部、（Ｃ）エラストマーを３〜７０重量部、および（Ｄ）水酸化マグネシウムを５０〜２５０重量部配合してなることを特徴とするポリフェニレンサルファイド樹脂組成物。（構造式中のａは５以上の自然数であり、ｂは７以上の自然数である。）【選択図】なし
