PROBLEM TO BE SOLVED: To provide a fiber-reinforced thermoplastic resin sheet that has reduced thermal expansion in thickness direction under a high temperature environment while using a thermoplastic resin as a matrix resin component.SOLUTION: A fiber-reinforced thermoplastic resin sheet contains a thermoplastic matrix resin, and glass fibers with a length of 3-25 mm, and heat-resistant resin fibers that have a negative thermal expansion coefficient, fusion or pyrolysis at a temperature lower than or equal to 260°C, and have a length of 0.1-1 mm, contained in the matrix resin.SELECTED DRAWING: Figure 5 【課題】マトリックス樹脂成分として、熱可塑性樹脂を使用しながらも、高温環境下での厚さ方向への熱膨張が低減した繊維強化熱可塑性樹脂シートを提供する。【解決手段】熱可塑性のマトリックス樹脂と、前記マトリックス樹脂中に含有されている、長さが３〜２５ｍｍのガラス繊維と、負の熱膨張係数を有し、かつ２６０℃以下の温度で溶融および熱分解しない、長さが０．１〜１ｍｍの耐熱性樹脂繊維とを含む繊維強化熱可塑性樹脂シート。【選択図】図５
