Abstract: A thixomolding material includes: a metal body that contains Mg as a main component; and a coating portion that is adhered to a surface of the metal body via a binder and contains SiC particles containing SiC as a main component. A mass fraction of the SiC particles in a total mass of the metal body and the SiC particles is 2.0 mass % or more and 40.0 mass % or less. The binder may contain waxes. A content of the binder may be 0.001 mass % or more and 0.200 mass % or less.
