PROBLEM TO BE SOLVED: To provide a damage sensing sheet capable of being easily mounted with high adhesiveness even when an inspected body has the complex shape, being easily and inexpensively replaced when it is broken, and exercising the superior standardization accuracy of a damaged position and the damage-state grasping function. SOLUTION: This damage sensing sheet is composed of a resin film comprising a piezoelectric element and an electrode circuit, and one piezoelectric element capable of generating the elastic wave and detecting the same, is mounted as the piezoelectric element.
