PROBLEM TO BE SOLVED: To provide an ultrasonic probe including a sound absorption layer where a groove enabling a piezoelectric layer to be installed therein is formed, and to provide a manufacturing method of the ultrasonic probe.SOLUTION: An ultrasonic probe comprises: a piezoelectric layer 20; and a sound absorption layer 30 positioned on a rear surface of the piezoelectric layer, the sound absorption layer 30 where a groove 31, allowing the piezoelectric layer to be installed, is formed on a front surface. The piezoelectric layer 20 is formed by multiple elements processed into a form of one of one dimensional array and two dimensional array and forms a ground electrode on at least one surface of the elements and a signal electrode on at least one surface including a surface opposite to the surface where the ground electrode is formed. The groove 31 is formed in the same form as the piezoelectric layer 20. |
