1. A polymer physical property prediction device comprising:
a processor; and
a memory storing program instructions that cause the processor to
read a structural unit from a storage unit and use the structural unit to calculate numbers each indicating how many substructures are in a polymer, the polymer being formed of repetition of the structural unit;
calculate a number indicating how many atoms are in the structural unit;
calculate number densities of the substructures from the numbers of substructures and the number of atoms in the structural unit;
construct a regression model that predicts a physical property value by using an experimental value of a physical property of the polymer and the number densities of the substructures, the experimental value being obtained from the storage unit;
input a polymer structure of which the physical property value is to be predicted; and
predict the physical property value corresponding to the input polymer structure by using the regression model.
