PROBLEM TO BE SOLVED: To provide an apparatus for designing a product shape capable of designing a product fitting in with the shape of an individual human body by considering constraints on design which a product should have or constraints for making the product fit in with the human body. SOLUTION: A product shape designing apparatus is provided with a measuring apparatus 101 to measure a human body shape A, a human body shape B and a product shape C, a pre-processor 102 for performing data conversion processing to express the human body shape A and the human body shape B with the same number of points and the coordinate points of the same geometrical structure and a calculation processor 103 for, based on the data of the human body shape A and the human body shape B data-converted by the pre-processor and the product shape C, calculating a deformation grid G to simultaneously minimize the inter-individual error of the human body shape A and the human body shape B and the error of the design target value of the peripheral length and cross-sectional peripheral length of a cross section H determined from the product shape C, and for applying the deformation grid G to the product shape C thereby acquiring a new product shape F fitting the human body shape B.
