Prepreg and fiber-reinforced composite material

The present invention has the following structure to provide a prepreg that makes it possible to produce a fiber-reinforced composite material provided with both exceptional impact resistance and thickness-direction conductivity. A prepreg characterized in containing at least the following components [A]-[F], and further characterized in that the ratio Ne/Nd of the number of structures Ne of component [F] present in a range of outside 110% of the particle diameter of component [E] and the number of structures Nd of component [F] present in a range outside 110% of the particle diameter of component [D] is 0.25 or higher. [A]: Carbon fibers, [B]: thermosetting resin, [C]: curing agent, [D]: particles composed mainly of thermoplastic resin having a primary particle number-average particle size of 5-50 [mu]m, [E]: conductive particles different from component [D] and having a primary particle number-average particle size in the range of a specific expression, [F]: filler comprising a carbon material 本发明为提供能够制造兼具优
