For the filled skutterudite compounds, high-pressure synthesis is thought to be a powerful technique, because it is possible to synthesize compounds that could not been grown by the flux method under ambient pressure and to improve the filling factor of rare-earth ions. In this article, we report the details of high-pressure synthesis of the filled skutterudite PrFe4Sb12 and the brief result of its physical properties. As a result, we have succeeded in synthesizing high-quality crystals of PrFe4Sb12 with higher Pr-filling factor and obtaining information about the crystalline electric field of PrFe4Sb12.
