PURPOSE: A device for sensing damage to a structure is provided to enable to extend a sensing domain with respect to the structure as a signal variation caused by impedance is clear in a region of low frequencies. CONSTITUTION: A device(1) for sensing damage to a structure(1) comprises an attachment unit(10), a vibration unit(20), and a measurement unit(30). The attachment unit is attached to the structure. The vibration unit is joined to the attachment unit and vibrates the structure. The measurement unit is connected to the structure, thereby measuring impedance. The attachment unit comprises metallic materials transmitting waves generated in the vibration unit. [Reference numerals] (30) Measurement unit
