摘要： An object of the present invention is to provide a prepreg capable of giving a fiber-reinforced composite material having both excellent mechanical characteristics and conductivity in the thickness direction thereof. The prepreg of the present invention is a prepreg including conductive fibers impregnated with a matrix resin, the prepreg being a prepreg having a conductive region where a conductive material is dispersed in the resin. In the present invention, it is preferred that a resin layer composed of at least the matrix resin is present on one or both surfaces of a conductive fiber layer composed of at least the conductive fibers, and the conductive region is present at least in the resin layer. In addition, it is preferred that the above-described conductive region is present continuously in the thickness direction. It is also preferred that the conductive region is a conductive region where the conductive material is dispersed in the matrix resin, and that the resin in the conductive region forms a continuous phase with the matrix resin in other regions. In the present invention, it is preferred that a volume resistivity of the conductive region is 1/1,000 or less of that of other regions of the matrix resin.
