Abstract
A carbonaceous substrate of the present invention is such that an X-ray diffraction pattern thereof is a complex profile and includes at least two (002) diffraction lines; and the substrates contains crystallites with different interlayer spacings. Further, in the X-ray diffraction pattern, (002) diffraction lines between 2θ=10° and 2θ=30° have an asymmetric shape; and the X-ray diffraction pattern includes at least two pattern components which are a diffraction line whose center is at 2θ=26° and a diffraction line whose center is at a lower angle than 2θ=26°. Further, the carbonaceous substrate contains crystals wherein the periodic distance dis 0.34 nm or more and the crystallite size Lcis 20 nm or less based on the X-ray diffraction lines. An electrodes for fluorine electrolysis of the present invention includes the carbonaceous substrate on which a conductive diamond thin film is formed.
