PROBLEM TO BE SOLVED: To provide a system and a method for directly measuring the amount of thermal deformation of a metallic die at a portion of a largest thermal deformation in such a hot state that the metallic die has been heated up to a high temperature by supplying molten metal into the casting metallic die and the metallic die has deformed up to a maximum. SOLUTION: The system for measuring the deformation of the metallic die comprises a detecting element unit 20 composed of a detecting element 21 and a detecting element jig 22; an element unit to be detected 30 composed of an element to be detected 31 having a portion 321 to be detected of the detecting element 21 on its one end side and a jig for the element to be detected 34; and a displacement meter 41 for measuring the displacement of the element to be detected 31 based on the detected value of the detecting element 21. The detecting element jig 22 is provided with a cooling mechanism for cooling the detecting element 21. The element to be detected 31 is composed of a rod shape member 32 supporting the portion to be detected 321 on its one end side, and a cylindrical member 33 into which the rod shape member 32 is slidably inserted, wherein the portion 321 to be detected is held by the jig for the element to be detected 34 such that the portion 321 faces to the detecting element 21, and also the other side end portion is brought into contact with a displacement measuring portion of the metallic die.
