    Abstract: A cellulose fiber-dispersing resin composite material, containing a cellulose fiber dispersed in a resin, in which a content of the cellulose fiber is 1% by mass or more and less than 70% by mass, and LL and LN satisfy the following [Expression 1], when a length weighted average fiber length of the cellulose fiber is taken as LL, and a number average fiber length of the cellulose fiber is taken as LN measured under the following measurement condition; a formed body using this composite material; and a composite member using this formed body. LL and LN are determined for a dissolution residue obtained by immersing the cellulose fiber-dispersing resin composite material in a solvent capable of dissolving the resin in the composite material, in accordance with Pulps-Determination of fiber length by automated optical analysis specified by ISO 16065 2001. 1.1

    Abstract: A fiber-dispersed resin composite material, containing fiber dispersed in a resin, wherein the content of the fiber in the fiber-dispersed resin composite material is 1 mass % or more and less than 70 mass %, and wherein the fiber-dispersed resin composite material has a maximum color difference A determined under conditions below of 0.05 or more and 6 or less:

    L*, a*, and b* values in CIE (L*a*b*) color space are measured on a straight line at 8 points with an interval of 1 cm by using a chromameter, and a color difference ΔE1 between measurement points linearly adjacent to each other is calculated by [Expression 1-1] below while a maximum value among 7 calculated values for the resulting color difference ΔE1 is set as the maximum color difference A, Δ ⁢ E ⁢ 1 = [ ( L i + 1 ⋆ - L i ⋆ ) 2 + ( a i + 1 * - a i * ) 2 + ( b i + 1 ⋆ - b i ⋆ ) 2 ] 0 . 5 [ Expression ⁢ ⁢ 1 ⁢ - ⁢ 1 ] where L*i, a*i, and b*i are the L*, a*, and b* values at i-th measurement point among the 8 measurement points, and i is an integer of 1 to 7 in [Expression 1-1].
