PURPOSE:To arrange plural piezoelectric vibrators for an ultrasonic wave probe in a circular form with high accuracy by bonding a flat piezoelectric master vibrator to a flexible film, cutting off it into plural piezoelectric vibrators being continuous via the film and fixing them in a way of a circular arc curve. CONSTITUTION:After a master external extracting electrode 22 is provided to the flat piezoelectric master vibrator 20, the vibrator is bonded to the flexible film 24, cutting slots 26 are formed at each prescribed interval succeedingly, and the vibrator is cut off into plural continuous piezoelectric vibrators 2 continuous via the film 24 and external extraction electrodes 32 corresponding to them. Then the vibrators are placed to a jig having a prescribed inner diameter while being fitted with the film 24 and a reinforcement member 8 is bonded to both side faces of the piezoelectric vibrator 2. Thus, the piezoelectric vibrators 2 are fixed in a circular arc curve while arranging the pitch. |
