PROBLEM TO BE SOLVED: To provide an inspection work support device, an inspection work support method, and an inspection work support program for improving the accuracy of inspection work. SOLUTION: An inspection work support device generates and displays a three-dimensional model image by synthesizing partial images of each part of a structure, and among the three-dimensional model images. A second generation unit that generates and displays an ortho image for a designated inspection region, and each region of the ortho image and the partial image that forms the region are displayed based on the correspondence relationship. It has a display unit that displays a partial image corresponding to the pointed position in the ortho image. [Selection diagram] Fig. 1
