    Abstract: [Problem] A problem to be addressed by the present invention is to provide a CFRP with a low risk of edge glow by virtue of controlling the structure of the CFRP and without relying on expensive electroconductive particles. In other words, provided is a CFRP such that the risk of edge glow is greatly decreased, even in a case where electroconductive particles are used in an amount equal to or smaller than in a conventional technology. Further provided is a CFRP such that the risk of edge glow is greatly decreased without using electroconductive particles.
    [Solution] A carbon-fiber-reinforced composite material including carbon fiber sheets containing unidirectionally arranged carbon fibers, laminated multidirectionally one on another, and impregnated with a matrix resin, which is cured; wherein, assuming that a region in which the carbon fibers have the same angle of fiber orientation consecutively in the thickness direction is defined as a Layer, and that, when the Layer is composed of a plurality of regions having a given thickness, and having different carbon fiber volume content factors (Vcf), each of the regions having a given thickness is defined as a Sublayer, the carbon fiber sheet contains a specific Layer that satisfies (1) to (3), and the thickness of a resin portion between the specific Layer and at least one Layer adjacent to the specific Layer is 5 μm or less; (1) the average Vcf of the Layer (hereinafter referred to as the Layer average Vcf) is 50% or more, (2) as both outermost parts of the Layer, Sublayers each having a Vcf the ratio of which to the Layer average Vcf is 0.5 or more (hereinafter, such a Sublayer is referred to as a high-Vcf Sublayer) are disposed, wherein each average Vcf is higher than the Layer average Vcf, and (3) between the high-Vcf Sublayers as both outermost parts of the Layer, a Sublayer having a Vcf the ratio of which to the Layer average Vcf is less than 0.5 (hereinafter, such a Sublayer is referred to as a low-Vcf Sublayer) exists.
