Provided are a composite material structure obtained by joining composite materials with resin-impregnated reinforcing fibers, for which appropriate lightning proofing measures are taken, and a method for manufacturing the composite material structure. The composite material structure includes a first composite material, a second composite material, and a low-conductivity material. The first composite material includes a conductive first reinforcing fiber and a first resin impregnated into the first reinforcing fiber. The second composite material is integrated with the first composite material, and has a conductive second reinforcing fiber and a second resin impregnated into the second reinforcing fiber. The low-conductivity material has an electrical resistance that is lower than that of the first resin and the second resin and a low conductivity that is greater than or equal to the first reinforcing fiber and the second reinforcing fiber, and electrically connects the first reinforcing fiber to the second reinforcing fiber.
