Thixotropic molding material, method of producing thixotropic molding material, and thixotropically molded product

A method of producing a thixotropic molding material comprising:

• a preparation step of preparing a mixture containing a metal body containing Mg as a main component, AlN particles containing AlN, silica particles, and a dispersion medium;
• a stirring step of stirring the mixture;
• and
• a drying step of adhering the AlN particles to a surface of the metal body via the silica particles by removing at least a part of the dispersion medium from the stirred mixture.

A thixotropically molded product comprising:

• a matrix portion containing Mg as a main component;
• a first particle portion dispersed in the matrix portion and containing AlN as a main component;
• a second particle portion dispersed in the matrix portion and containing Mg2Si as a main component;
• and
• a third particle portion dispersed in the matrix portion and containing MgO as a main component, wherein
• an area fraction of the first particle portion in a cross section is 1.6% or more and 18.1% or less.
