A casting solidification analysis method, which can analyze positions of shrinkage cavities more accurately than in the past, a casting method using the above method, and an electronic program are provided. A following casting solidification analysis method is provided. An amount of expansion/shrinkage for each solidification step length separated by inflection points in a cooling curve is determined, by setting a solid phase ratio at a completion of pouring to 0, setting a solid phase ratio at an end of solidification to 1.0, and determining the expansion/shrinkage amount for the each solidification step length by proportionally distributing the each solidification step length to the total solid phase ratio length.

An electronic program comprised from;
A solidification analysis method, which analyses shrinkage and expansion temperatures at an early stage of solidification and shrinkage temperature at an end of solidification by connecting a latent heat pattern released during solidification by a straight line from solid phase ratio 0 to 1.0.
