摘要： A method for measuring a film strength of a film on an object. An incident angle of pressure waves with respect to an object to be measured, the object including a base coated with a film, is set for applying the pressure waves to the object. The incident angle is varied over a range including a critical angle θcr. The object generates surface waves, in response to the pressure waves, at and near the critical angle. In response to the surface waves, the object generates leaky waves, which are pressure waves caused by the surface waves. The intensity of pressure waves including reflected waves and leaky waves from the object are measured. A received intensity V0 at an incident angle where no leaky wave is generated, and the intensity difference VC between V0 and the received intensity at the critical angle θcr when the film strength is high are measured. An intensity difference VR between V0 and the received intensity when the intensity of the leaky waves remains unchanged, regardless of the changes in the incident angle, within the range where the leaky waves are generated, which indicates a low film strength, is also measured. Thus, the film strength is determined based on V0, VC, and VR.
