PROBLEM TO BE SOLVED: To provide a fault tree generation device that generates a fault tree of high precision from less fault information in the case of generating the fault tree from information on trouble occurring in an operation stage.SOLUTION: A fault tree generation device according to one embodiment of the present invention includes: an information narrowing-down unit which narrows down fault information to be used to generate a fault tree from among a plurality of pieces of fault information as instructed by a user; a fault tree generation unit which generates one or a plurality of fault trees from the fault information narrowed down by the information narrowing-down unit; a fault tree selection unit which allows the user to select a fault tree to be saved from among the one or plurality of generated fault trees; and a fault tree saving unit which saves the fault tree(s) selected by the user in a storage unit.SELECTED DRAWING: Figure 1
