1. A non-transitory computer readable medium storing an inspection program for a molded article region, the inspection program causing a processor to execute:
a step of performing machine learning of mechanical property information and nondestructive inspection information of a fiber-reinforced first molded article region, and generating a mechanical property inference model in which nondestructive inspection information of a fiber-reinforced second molded article region is input for inferring unknown mechanical property information of the second molded article region;
a step of acquiring the nondestructive inspection information of the second molded article region; and
a step of inputting the acquired nondestructive inspection information into the mechanical property inference model, acquiring the mechanical property information of the second molded article region from the mechanical property inference model, and performing output based on the mechanical property information, wherein
the first molded article region and the second molded article region are both obtained by molding a plate-shaped composite material with a mold, and
the first molded article region and the second molded article region are both obtained by molding the composite material such that a charge rate is 10% or more and 500% or less,
wherein the charge rate is a value obtained by calculating (S1/S2)×100,
wherein S1 is a projection area of the composite material, and S2 is a projection area of a portion corresponding to each of the first molded article region and the second molded article region in a mold cavity of the mold.
