Abstract

See full text

The present invention provides a method for inspecting a material to be inspected using ultrasound waves, the method including the following step 201 to step 301, in which step 201 is performed in a condition where: the surface temperature of a material under inspection—atmospheric temperature>2° C., and inspection using ultrasound waves in step 301 satisfies: a refractive attenuation rate≤1.5%. Step 201: blowing a fluid from a blowing port onto the material to be inspected. Step 301: inspecting the material to be inspected using the ultrasound waves after step 201 or at the same time as the step 201.
