Abstract
A highly transparent fiber composite material is provided that can be manufactured through a simplified process using reduced amounts of raw materials and that has high flexibility and low thermal expansivity and retains good functionality of the fiber material. The fiber composite material includes: a fiber assembly having an average fiber diameter of 4 to 200 nm and a 50 μm-thick visible light transmittance of 3% or more; and a coating layer that coats and smoothes the surface of the fiber assembly, wherein the fiber composite material has a 50 μm-thick visible light transmittance of 60% or more. With this fiber assembly, the scattering of light caused by the irregularities on the surface can be suppressed by coating the surface with the coating layer to smooth the surface, whereby a highly transparent fiber composite material can be obtained.
