PROBLEM TO BE SOLVED: To provide a method of molding semisolid metal by pressurization without taking complicated steps and provide a die used in the method. SOLUTION: A die to be used is provided with a lower die having a concave part which is large enough to accommodate semisolid metal and a upper die, and semisolid metal is filled in a space formed by them and moreover, if necessary, by a slide core and a casting product is molded. Semisolid metal having minute spherical crystal with a solid phase rate ranging from 30% to 99.9% is accommodated in the concave part of the lower type die and is filled in a space for a product formed by the transfer of the upper die, the lower die and, if necessary, the slide core.
