Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a casting article hardly having insulation defects by attaching a temperature gradient to a casting die. SOLUTION: The casting die is equipped with: a movable side die 2 having a cavity 3 and an injection port 4; a movable side hot plate 9 fixing the movable side die 2 and having a temperature controlling means; a fixed side die 12 having a cavity 13 and an injection port 14, and a fixed side hot plate 19 fixing the fixed side die 12 and having a temperature controlling means. The movable side die 2 and the fixed side die 12 are characterized in that the temperatures of the parts far from the injection ports 4, 14 are higher, the temperatures of the parts near the injection ports 4, 14 are lower, and the temperature gradient per unit length is linear.
