To provide a sheet for a fiber-reinforced resin molding that is for manufacturing a fiber-reinforced resin molding having an improved hue in spite of enhanced strength and rigidity due to a cellulose fiber.SOLUTION: A sheet for a fiber-reinforced resin molding contains a cellulose fiber of 40-94 mass%, a resin for fiber dispersion of 5-59 mass%, and titanium oxide particles mainly containing rutile-type titanium dioxide of 1-5 mass%. A method of manufacturing a fiber-reinforced resin molding includes melt mixing a ground product of a fiber-reinforced resin molding sheet and a base resin to be the main component of a matrix resin for molding.SELECTED DRAWING: None 【課題】セルロース繊維によって強度及び剛性を向上させているにもかかわらず、色味が改善された繊維強化樹脂成形体を製造するための繊維強化樹脂成形体用シート提供する。【解決手段】本発明の繊維強化樹脂成形体用シートは、セルロース繊維４０〜９４質量％と、繊維分散用樹脂５〜５９質量％と、ルチル型酸化チタンを主成分とする酸化チタン系粒子１〜５質量％とを含有する。本発明の繊維強化樹脂成形体の製造方法は、本発明の繊維強化樹脂成形体用シートの粉砕物と、マトリックス樹脂の主成分となるベース樹脂とを溶融混練して成形する。【選択図】なし
