A molten alloy solidification analyzing method of the invention is characterized in that the amount of change in fraction solid is calculated based on the solidification rate of molten alloy and the solidification rate parameter that is a parameter for evaluating the influence of the solidification rate on solidification of the molten alloy, according to the fraction solid. By conducting such a simulation that takes into consideration the supercooling, a highly accurate solidification analysis is relatively easily performed for various molten alloys.

A mold includes: a base; and a contact surface which is provided on the base and which comes into contact with a molten material. The contact surface is provided with a first surface portion that includes a first fiber layer in which first carbon fibers are raised, and a second surface portion having different surface characteristics from the first surface portion.
