Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a nonwoven fabric that can be used as a supply source of fibers of a fiber-reinforced thermoplastic resin sheet with reduced thermal expansion in thickness direction.SOLUTION: A glass fiber nonwoven fabric contains glass long fibers with a length of 3-25 mm and glass short fibers with a length of 0.3-1 mm, in a mass ratio of 50:50-90:10. The glass long fibers are oriented horizontally with respect to the plane direction of the glass fiber nonwoven fabric, and at least part of the glass short fibers is inserted inside at an angle of 60-120 degrees with respect to the plane direction of the glass fiber nonwoven fabric.SELECTED DRAWING: Figure 1 【課題】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の繊維の供給源として用いることができる不織布を提供する。【解決手段】長さが３〜２５ｍｍのガラス長繊維と長さが０．３〜１ｍｍのガラス短繊維とを、質量比で５０：５０〜９０：１０の範囲で含むガラス繊維不織布であって、前記ガラス長繊維は、前記ガラス繊維不織布の平面方向に対して水平に配向し、前記ガラス短繊維の少なくとも一部は、前記ガラス繊維不織布の平面方向に対して６０〜１２０度の角度を持って内部に挿入されていることを特徴とするガラス繊維不織布。【選択図】図１
