Abstract

According to one embodiment, a structure evaluation system includes a wave guide, a first sensor, a second sensor, and a calculation part. The wave guide is formed in a rod shape, is inserted into a hole that is formed at a predetermined depth from a surface of a measurement target, and has one end fixed to a deepest portion of the hole. The first sensor is provided at the other end of the wave guide at a position that is substantially the same as the surface. The second sensor is provided on the surface of the measurement target. The calculation part estimates a depth of damage occurring in the measurement target from the surface on the basis of a first detection value of an elastic wave transmitted to the measurement target which is detected by the first sensor through the wave guide and a second detection value obtained by an elastic wave which is detected by the second sensor.
