More Information
Summary:An ultrasonic transceiver includes: piezoelectric body (2) including opposing surfaces having first electrode (2c) and second electrode (2d) respectively, piezoelectric body (2) being segmented into a plurality of elements (2a,2b) by groove (3) recessed from a surface having first electrode (2c) among the opposing surfaces; conductor (1) electrically connected to first electrode (2c) on each of elements (2a,2b). The ultrasonic transceiver further includes reinforcement section (7) provided in a part of second electrode (2d), the part corresponding to a bottom of groove (3). With this configuration, a decrease in a strength of piezoelectric body (2) in the bottom of groove (3), which is caused by groove (3) provided in piezoelectric body (2), can be prevented and occurrence of a crack can be prevented.
