PROBLEM TO BE SOLVED: To provide an inorganic composite whose design characteristics is improved by roughening its surface and whose flexural strength is increased without increasing the mass per a unit area. SOLUTION: This inorganic composite is composed of an inorganic matrix and reinforcing fibers, and the inorganic matrix comprises (AlPO<SB>4</SB>)-(Na<SB>2</SB>O)<SB>x</SB>(x=0.08 to 0.38) and Al<SB>2</SB>O<SB>3</SB>. The inorganic matrix comprises (AlPO<SB>4</SB>)-(Na<SB>2</SB>O)<SB>x</SB>(x=0.08 to 0.38) of 30 to 70 mass%. The inorganic matrix comprises Al<SB>2</SB>O<SB>3</SB>of 20 to 60 mass%. The inorganic matrix further comprises CaO-SiO<SB>2</SB>of 0.1 to 10 mass%. COPYRIGHT: (C)2004,JPO
