To provide a resin fiber, a method for manufacturing a fiber board, and a method for manufacturing a molding. which suppress defects due to static electricity when a fiber board and a molding are manufactured.SOLUTION: A resin fiber 1 has a sheath-core structure, a core part 11 contains an acid-modified polyolefin resin and a non-modified polyolefin resin, and a sheath part 12 contains a non-modified polyolefin resin and does not contain acid-modified polyolefin. A method for manufacturing a fiber board includes the steps of: forming a fiber mat containing vegetable fibers and resin fibers 1; and heating the fiber mat and melting the resin fiber 1, then solidifying the melted thermoplastic resin, and obtaining a binder resin. A method for manufacturing a molding includes a step of molding a fiber board obtained by the method for manufacturing the fiber board.SELECTED DRAWING: Figure 1 【課題】繊維ボードや成形体の製造時に静電気に起因する不具合を抑制する樹脂繊維、繊維ボードの製造方法及び成形体の製造方法を提供する。【解決手段】樹脂繊維１は、芯鞘構造を有し、芯部１１が、酸変性ポリオレフィン樹脂及び非変性ポリオレフィン樹脂を含み、鞘部１２が、非変性ポリオレフィン樹脂を含み、酸変性ポリオレフィン樹脂を含まない。本繊維ボードの製造方法は、植物繊維と樹脂繊維１とを含んだ繊維マットを形成する工程と、繊維マットを加熱して樹脂繊維１を溶融させた後、溶融された熱可塑性樹脂を固化してバインダ樹脂を得る工程とを備える。本成形体の製造方法は、本繊維ボードの製造方法により得られた繊維ボードを成形する工程を備える。【選択図】図１
