To provide a casting apparatus wherein a sprue of a die can be maintained constantly at a high temperature, any molten metal basin for heating the sprue is not required, any return of the molten metal to a furnace side for each release is not required, the casting cycle can be shortened, and any oxide is hardly generated in the molten metal.
In the casting apparatus, a molten metal is filled in a die 4 from a molten metal tank where the metal is stored in a molten state via a stoke 8, and then the molten metal is solidified in the die 4 to form a casting. A flow passage of the molten metal before reaching a sprue 9 of the die 4 is surrounded by a heat storage body 17 to be heated by a heater 18. A ceramic coating is executed on the flow passage of the molten metal before reaching the sprue 9 of the die 4.
