A method for refining inorganic short fibers at a high yield rate. In the refining method of inorganic short fibers according to the present invention, an electric field is applied to dielectric liquid in which inorganic short fibers that include impurities are dispersed. The inorganic short fibers to which the electric field is applied are polarized and bonded with each other. The inorganic short fibers in the dielectric liquid are caused to fall. The falling inorganic short fibers are collected separately from the falling impurities utilizing the difference between the falling rate of the bonded inorganic fibers and the falling rate of the impurities.

First, a melt of Al or a melt of an Al alloy containing Si is injected in a die filled with SiC powder and cast to form a plate member made of an Al/SiC composite. Next, an Al foil member made of an Al&#x2014;Mg-based alloy is joined with the surface of the plate member through hot pressing. As a result, part of the Al foil member enters casting blowholes on the surface of the plate member to fill the casting blowholes. In addition, an Al&#x2014;Mg-based alloy layer is formed on the surface of the plate member. Thus, a base plate having a nearly flat surface is produced.

A low-expansion unit includes a plate member and an iron-nickel layer. Upper and lower surface layers of the plate member each have the iron-nickel layer thereon and/or therein. While the plate member has a relatively large thermal expansion coefficient, the iron-nickel layers, which are formed on and/or in the upper and lower surface layers of the plate member, have a relatively small thermal expansion coefficient. Therefore, thermal expansion coefficient of the low-expansion unit is as a whole restrained to a relatively small value. Also, the plate member includes pure iron whose thermal conductivity is relatively high. Meanwhile, the iron-nickel layers, which are formed on the plate member, are relatively thin. Therefore, the low-expansion unit has a relatively large thermal conductivity in a direction of thickness thereof.
