The invention is to offer a composite material with least uneven distribution of a mechanical strength resulted from dispersing conditions of an inorganic filler and having a by far high mechanical strength in comparison with conventional composite materials, as well as to offer a method of making the same. Inorganic hollow particles and at least one of inorganic fiber sheets are accommodated in a stacked manner within a casting mold, and a molten metal is poured into a casting mold while pressurizing it, followed by cooling, whereby it is possible to produce such a composite material where a first composite layer and a second composite layer continuously exist in a metal matrix, so as to compose a composite material being a single body as a whole, the first composite layer containing at least one of inorganic fiber sheets and the second composite layer containing inorganic hollow particles.
