In a method for estimating flange displacement amount, effective three-dimensional coordinate data at a lower first position on a surface continuous with a lower flange surface of a first supported portion and at an upper first position coincident with the lower first position in the horizontal direction on a surface continuous with an upper flange surface are determined. The effective three-dimensional coordinate data at the respective positions are changed such that the effective three-dimensional coordinate data at the lower first position and the effective three-dimensional coordinate data at the upper first position are coincident with each other. In accordance with a difference between a position in a vertical direction indicated by the effective three-dimensional coordinate data at an upper target position on the upper flange surface after a coordinate change and a position in the vertical direction indicated by the effective three-dimensional coordinate data at a lower target position on the lower flange surface after a coordinate change, displacement amounts of the upper target position and the lower target position in the vertical direction when a state changes from an open state to a fastened state are obtained.
