    • The invention provides a carbon fiber-reinforced composite material including reinforcing fibers which are continuous carbon fibers in the form of a unidirectional (UD) material, a woven fabric, or a knitted fabric, and a matrix resin including a modified polyolefin resin, thereby achieving better adhesion and mechanical strength. The matrix resin forms a polyphase structure having a sea-island structure which has an average island (independent phase) diameter of not greater than 0.5 μm. The composite material includes as a matrix resin a modified polyolefin resin obtained by, for example, graft-modifying a polyolefin resin with a monomer that contains an ethylenic double bond and a polar group in the same molecule; and includes as reinforcing fibers continuous carbon fibers. For example, the fiber-reinforced composite material is obtained by stacking the modified polyolefin resin and carbon fibers in a mold with a predetermined shape, and impregnating the carbon fibers with the modified polyolefin resin in a molten state under pressure, followed by cooling and curing.
