PURPOSE:To perform high speed signal transmission as well as microsignal transmission, by using a substrate which is equipped with an electrical element which is formed with superconducting ceramic materials having an oxygen deficiency type perovskite structure as well as with an insulation layer which is formed of insulation materials having the same composition components, yet having different composition ratios. CONSTITUTION:This substrate is equipped with an electrical element 1 and an insulation layer 2 and then, the electrical element 1 is formed of superconducting ceramic materials having an oxygen deficiency type perovskite structure and the insulation layer 2 is formed of insulation materials which have the principal components consisting of the same composition components but of different composition ratios and further, its insulation layer 2 is provided by coming into contact with the electrical element 1. As the insulation materials have the same composition components as those of the superconducting ceramic materials, the foregoing materials suppress the breakdown of superconducting structure which is caused by a reaction to the superconducting ceramic materials of the electrical element 1 when the reaction takes place in a process of burning. Thus, reflection is prevented and high speed signals wherein distortion is prevented from occurring are transmitted and accordingly microsignals may also be transmitted. |
