PURPOSE:To achieve non-destructive inspection in a civil structure such as an asphalt or concrete paved road having a rough surface to be inspected with a high sensitivity and an improved stability using ultrasonic wave by a tire probe. CONSTITUTION:In a tire probe which performs non-destructive inspection of an object to be inspected by receiving and transmitting ultrasonic wave-using an ultrasonic probe which is laid out within a tire 2 while rotating the tire 2 on an object to be inspected, a rubber tire 3 where a gel sheet 4 which is formed by a macromolecular gel-shaped elastic body on the outer-periphery surface contacting the object to be inspected and a water-film forming means for forming a water film between the surface of the gel sheet 4 of the rubber tire 3 and an inspection surface are provided. Ultrasonic wave is propagated to the object to be inspected via the gel sheet 4 and the water film 24. |
