ABSTRACT:
An ultrasonic probe is provided which includes a piezoelectric vibrator having an earth electrode and a signal electrode on a rear surface, an acoustic matching layer disposed on a front surface side of the piezoelectric vibrator, a packing material disposed on the rear surface of the piezoelectric vibrator, and a flexible printed circuit that is interposed between the piezoelectric vibrator and the packing material to cover the entire rear surface of the piezoelectric vibrator and has an earth wiring layer and a signal wiring layer. The earth wiring layer and the signal wiring layer are exposed from a surface facing the piezoelectric vibrator of the flexible printed circuit so as to be electrically connected to the earth electrode and the signal electrode through an exposed surface of the earth wiring layer and an exposed surface of the signal wiring layer, respectively.
