PURPOSE: To provide a high pressure solidification casting die by which directive solidification progressing toward a pressurizing part from a product part can be realized.

CONSTITUTION: This high pressure solidification casting die is provided with a pressurizing part 4 for pressurizing supplied molten metal 8, a product part 5 for forming the product and a runner part 9 connecting the above-mentioned pressurizing part 4 and the product part 5, respectively and the opening hole cross sectional areas of the runner fitting hole 9a at the pressurizing part 4 side and the runner fitting hole 9b at the product part 5 side, are formed as the same, and also, the circular length of the cross sectional shape in the runner part 9 is formed so as to gradually lengthen toward the product part 5 side from the pressurizing part 4 side.
