Zusammenfassung:	To provide: a thixotropically molded product that is high in the wear resistance and mechanical strength; a thixotropic molding material allowing production of such a thixotropically molded product; and a method of producing the same.SOLUTION: A thixotropically molded product includes: a matrix portion containing Mg as a main component; and a first particle portion dispersed in the matrix portion and containing c-BN or w-BN as a main component. The average particle diameter of the first particle portion in a cross section is 10.0 μm or less, and the area fraction of the first particle portion in the cross section is from 2.0% to 20.0% inclusive.SELECTED DRAWING: Figure 5 【課題】高い耐摩耗性および高い機械的強度を有するチクソ成形体、ならびに、かかるチクソ成形体を製造可能なチクソ成形用材料およびその製造方法を提供すること。【解決手段】Ｍｇを主成分とするマトリックス部と、前記マトリックス部に分散し、ｃ－ＢＮまたはｗ－ＢＮを主成分とする第１粒子部と、を有し、断面における前記第１粒子部の平均粒径は、１０．０μｍ以下であり、断面における前記第１粒子部の面積分率は、２．０％以上２０．０％以下であることを特徴とするチクソ成形体。【選択図】図５
