To provide an insulation structure that insulates carbon fiber or carbon nanofiber as a high thermal conductor and has high strength and is durable against high temperature.
A holding carrier 10 or a holding carrier 6b is formed by sintering an insulative material, e.g. silicon dioxide (SiO2) powder. For example, a heat transmissive fiber flux 6a wherein cross sections are arranged as plane is piled up on the insulative holding carrier 10 as shown in the diagram 3 (A). In addition, as shown in the diagram 3 (B), the insulative holding carrier 10 is piled up on the upper and lower sides of the heat transmissive fiber flux 6a wherein cross sections are arranged as plane. Furthermore, as shown in the diagram 3 (C), the holding carrier 6b covers the vicinity of the heat transmissive fiber flux 6a wherein cross section are arranged like plane.
