摘要： The present invention provides a carbon-fiber-reinforced composite material having excellent tackiness, excellent compatibility with epoxy resins, and excellent interfacial adhesion while being capable of achieving high mechanical strength and reducing the occurrence of voids, and a method for producing a carbon-fiber-reinforced composite material. Provided is a carbon-fiber-reinforced composite material containing: carbon fibers; an epoxy resin; a curing agent; and a thermoplastic resin, wherein a mixture of the epoxy resin and the thermoplastic resin has a ratio of viscosity at 30° C. to viscosity at 90° C. (viscosity at 30° C./viscosity at 90° C.) of 100 or greater.
