PROBLEM TO BE SOLVED: To provide a composite material including a carbon fiber structure capable of improving physical characteristics such as electrical characteristics, mechanical characteristics, thermal characteristics and the like, without impairing the characteristics of a matrix with a small amount of addition. This is the issue. A three-dimensional network-like carbon fiber structure composed of carbon fibers having an outer diameter of 15 to 100 nm, wherein the carbon fiber structure has a configuration in which a plurality of the carbon fibers extend. The carbon fiber structure, which is formed in the process of growing the carbon fibers, is formed in a matrix at a ratio of 0.1 to 30% by mass. A composite material characterized in that it is contained therein. [Selection] Figure 8 |
