A three-dimensional model creating device creates an individual model indicating an individual shape of an object from an integrated model created based on data obtained by capturing images of or measuring at least two or more objects together. The three-dimensional model creating device includes: a three-dimensional model division processing unit configured to create a plurality of divided models obtained by dividing the integrated model by an extension plane extended from each plane configured to form the integrated model; a user interface unit configured to receive tagging of each of the divided models; and an individual model creating unit configured to create the individual model of the object based on the tagging of each of the divided models.
