PROBLEM TO BE SOLVED: To visualize and measure an earthquake impactive force acting on an underground object of a structure. SOLUTION: A pressure-sensitive color developing agent 5 formed by encapsulating dye or pigment in a plurality types of white, opaque micro capsules 8, which differ in breaking strength, is provided at an impact force measuring part of an underground pile 2 being an object to be inspected. The micro capsules are broken in accordance with the earthquake impact force received at the impact force measuring part. The dye or pigment is thereby released, thereby measuring the earthquake impact force the underground pile received through the color optical density of the pressure-sensitive color developing agent which develops a color.
