摘要： The present invention relates to a continuous carbon fiber bundle that is easily divided by cutting to a length of 25.4 mm, a sheet molding compound (SMC), and a fiber-reinforced composite material to be molded using the same. The SMC includes carbon fiber bundles including carbon fibers with a single fiber fineness of 1.0 dtex or more and 2.4 dtex or less and a matrix resin composition. In the SMC, a mode value in a mass distribution of carbon fiber bundles with respect to a mass of individual carbon fibers bundle is 50% or less of the mass of the carbon fiber bundle with the largest mass, and additionally, a fiber-reinforced composite material molded using the same is used to address problems.
