摘要： A carbon fiber-reinforced molded article includes an arranged composite material and a cured resin product. The composite material includes a carbon fiber bundle and carbon nanotubes. The carbon fiber bundle is in which a plurality of continuous carbon fibers are arranged. The carbon nanotubes adhere to respective surfaces of the carbon fibers. A modulus of elasticity obtained by conducting a three-point bending test with a cushioning material is smaller than a modulus of elasticity obtained by conducting the three-point bending test without the cushioning material.
