Abstract:  
Disclosed is an apparatus for detecting at least one of an intensity and a density of shot blasting during shot treatment, which includes a shot bombardment and propagation member including a first part to be bombarded by a shot stream for generating elastic waves when bombarded by the shot stream and a second part for propagating the elastic waves therethrough, a transducer for receiving the elastic waves from the shot bombardment and propagation member and transducing the elastic waves into a high-frequency electrical signal, and a measuring circuit detecting at least one of the number of times of shot bombardment and the inensity of shot bombardment on the basis of the high-frequency electrical signal.
