PROBLEM TO BE SOLVED: To provide a composite material, a production method of the same material and a composite structure which greatly change the thermal conductivity and the electric conductivity, and are applied for various heat receiving surface, heat radiation surface, etc. SOLUTION: The composite material 5 has in a mixed state an area 101 consisting of a material A and a material 103 consisting of a material B, in which at least one of the thermal conductivity and the electric conductivity of the material B is lower than that of the material A and the thermal expansion rate of the material B is also lower than that of the material A, wherein when the temperature being equal to or more than a determined temperature range, contact frequency between the areas 101 consisting of the material A increases and the values of the characteristics of the composite material 5 are higher compared with the case when the temperature being less than the determined temperature range.
