PROBLEM TO BE SOLVED: To provide a composite material and a production method of the material having little decrease in mechanical strength, improved conductivity and resistance to lightening strikes.SOLUTION: The composite material is a prepreg of a polymer resin layer and a fiber reinforcement material. The polymer resin layer contains conductive particles by 0.2 vol.% to 20 vol.% of the composite material; at least 50% of the conductive particles have a size ranging from the polymer resin layer thickness up to 10 μm; and the particles are, for example, metal-coated particles having a core-shell structure. |
