PROBLEM TO BE SOLVED: To provide a manufacturing method for a human body affected part entity model which is suitably utilized for rehearsal and simulation of actual operation in the same way as conventional entity model while reducing the amount of use of an expensive photosetting resin as far as possible. SOLUTION: A number of two-dimensional cross sectional image data are obtained over the whole affected part by MRI or CT scanning and then, on the basis of the image data, a hardened layer matching the contour shape of each cross sectional image is formed by making only a band corresponding to the contour section of each two-dimensional cross sectional image in the liquid photosetting resin be irradiated with an active ray. When the human body affected part entity model is formed by sequentially laminating each formed hardened layer to perform three-dimensional stereo lithography, a horizontal plane real edge line is extracted from the two-dimensional cross sectional image and then, a virtual edge line is drawn with a predetermined interval in a normal direction on the horizontal plane from the real edge line, and the two-dimensional linked region surrounded by the real edge line and the virtual edge line is consecutively formed to make a three-dimensional linked region, and, thereby, the human body affected part entity model is manufactured.
