Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a ceramic composite material that has a heat resistant property and an anti-corrosion property to high temperature steam without the use of radioactive elements, elements having toxicity, or rare elements, and to provide a process for producing ceramic composite material.SOLUTION: The ceramic composite material of the present invention is characterized by comprising a substrate made of SiC and a carbon nanotube layer made of carbon nanotubes covering the surface of the substrate. The process for producing ceramic composite material of the present invention is characterized by comprising a surface decomposition step in which a substrate made of SiC is heated in a vacuum or a CO atmosphere to form a carbon nanotube layer made of carbon nanotubes covering the substrate.SELECTED DRAWING: Figure 1 【課題】放射性の元素、毒性を有する元素、希少な元素を用いることなく、耐熱性および高温水蒸気に耐食性を有するセラミック複合材およびセラミック複合材の製造方法を提供すること。【解決手段】本発明のセラミック複合材は、ＳｉＣからなる基材と、前記基材の表面を覆うカーボンナノチューブからなるカーボンナノチューブ層と、からなることを特徴とする。本発明のセラミック複合材の製造方法は、ＳｉＣからなる基材を、真空中またはＣＯ雰囲気中で加熱することにより、前記基材を覆うカーボンナノチューブからなるカーボンナノチューブ層を形成する表面分解工程からなることを特徴とする。【選択図】図１
