PROBLEM TO BE SOLVED: To provide a fiber reinforced resin antenna which has high efficiency in reception and transmission because conductivity is high and anisotropy is small with respect to conductivity, is stable with little fluctuations and has high strength and high durability. SOLUTION: This fiber reinforced resin antenna has a multilayer structure overlapped with cylindrical carbon layers wherein a fiber diameter is 0.5 to 300 nm, fiber length is≤1000μm and an aspect ratio is 3 to 500, and is made of molding of a mixture including thin carbon fiber in an amount of 1 to 80 mass% and resin in an amount of 99 to 20 mass%, the central axis of which has a hollow structure, wherein volume resistivity is desirably≤10<SP>9</SP>Ωcm and impact strength is≥0.1 kg×cm/cm.
