1. A thixomolding material comprising:
a metal body containing magnesium (Mg) as a primary component; and
a coating layer covering an entirety of an outer surface of the metal body, the coating layer including a plurality of coating particles that each have an average particle diameter equal to or less than 100 μm, and the plurality of coating particles being made of an inorganic material differing from the metal body;
wherein the coating layer includes a plurality of interposed particles dispersed in a binder that are interposed between the metal body and the plurality of coating particles, the interposed particles each having an average particle diameter smaller than the plurality of coating particles, and the interposed particles being made of an inorganic oxide that is at least one of alumina and zirconia, and
wherein the binder includes a wax.
