Abstract
A surface treatment layeris formed on a surfaceof a through-holeso that the surfacehas an angle X of contact with solution L which is smaller than an angle Y of contact of a dieper se with the solution L. When the solution L is applied, the wetting action of the solution L relative to the through-holeis improved so that the solution L can be extended over the surface treatment layer, eventually over the entire surface of the through-hole. Consequently, the entire surface thereof can be formed with a crystallized layer by performing water evaporation. As a result, molding at higher temperature can be realized, and high-density compacts can be stably obtained. Further, the solution L in which the lubricant is dissolved in a solvent into a homogeneous phase, is applied to a molding portionA, and then evaporated to thereby form crystals thereon, thus forming the crystallized layer.
