PROBLEM TO BE SOLVED: To retrieve partially similar three-dimensional model as well by utilizing relevance of partial elements set in the three-dimensional model. SOLUTION: A retrieval part 24 reads relevance information among a plurality of partial elements included in the three-dimensional model of a retrieval target registered in a database 21, calculates featured values of the partial elements (a step S202) and simultaneously calculates the featured values from a three-dimensional model to be a retrieval key specified by an operation of an input part 10 (a step S201). Then, degrees of similarity are calculated by every partial element by using the calculated featured values (a step S203) and display output is performed in an output part 30 by sorting the partial elements of the respective three-dimensional models based on the calculated degrees of similarity and transmitting them to a retrieval result display part 25 as a retrieval result.
