PURPOSE: To provide the process for production of the functionally gradient material which can easily produce materials of a large volume and irregular- shaped materials of columnar, cylindrical and other shapes with less restrictions on the sizes and shapes of the functionally gradient material.

CONSTITUTION: This process consists of a first stage for forming a porous body in which the gap parts change gradually in prescribed directions by particles 1, 2, 3 of plural kinds of the materials constituting the functionally gradient material and a second stage of force feeding the remaining materials into the gap parts of this porous body, then curing the materials.
