To provide a measurement method for measuring vibration characteristics of a coupling part between a structure and a vibration testing machine, even when there is no general-purpose vibration testing machine.

When a vibration testing machine substitution member having a resonance frequency of a first bending mode larger than a frequency range of the structure is fixed to the structure, a coupling member having the characteristics equivalent to that in the case in which the structure is coupled to a vibration testing machine, is used between the structure and the vibration testing machine substitution member, and a coupling force equivalent to the case in which the structure is coupled to the vibration testing machine, is imparted to the coupling member to fix it to the structure. Thereafter, the whole of the structure, the coupling member, the vibration testing machine substitution member is excited so that the vibration characteristics of the coupling part between the structure and the vibration testing machine substitution member are measured.
