To provide a composite material structure in which a composite material in which a reinforced fiber is impregnated in a resin is conjugated, proper lightning countermeasure is conducted, and a manufacturing method of the composite material structure.SOLUTION: A composite material structure 10 includes a first composite material 11, a second composite material 12, and a low conductive material 13. The first composite material 11 has a first reinforced fiber having conductivity and a first resin impregnated into the first reinforced resin. The second composite material 12 has a second reinforced fiber integrated with the first composite material 11 and having conductivity, and a second resin impregnated into the second reinforced fiber. The low conductive material 13 has electrical resistance which is lower than the first resin and the second resin, and low conductivity which is larger than the first reinforced fiber and the second reinforced fiber, and electrically connects the first reinforced fiber and the second reinforced fiber.SELECTED DRAWING: Figure 1
