A molded product of the above, that is, a fatty acid metal salt which has been blocked in advance is prepared, and inserted into the mold 7,
You may press it. In this case, compared to the case where the powdered fatty acid metal salt 6 is injected into the mold 7,
Since the bulk density is very small, the mold 7 can be reduced in size, and the bulk fatty acid metal salt can be injected into the cavity 7a of the mold 7, and the powdered fatty acid metal salt 6 is injected. The handling such as injection into the mold 7 can be made easier than in the case. In the production of the molded article having the substantially final shape, since the pressing is performed by the mold 7 thereafter, the strength and the presence or absence of cracks are not required. Good.
Further, as a mold for obtaining a molded product having a substantially final shape, the same mold as the mold 7 for producing a finally required shape may be used.
