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: <Conditions> 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,
