This paper describes the basic study on measurement of guided waves using piezoelectric film. Over the past few years, nondestructive inspections using guided waves were performed. In the inspection, piezoelectric ceramics are used mainly. Since a piezoelectric film also has a piezoelectric effect and flexibility, it is available for the inspection. Then, an experiment using the piezoelectric film was performed. The results show that the echo obtained by piezoelectric film agrees with those obtained by the conventional method.
