Sound damping component for ultrasonic probe, ultrasonic probe, and ultrasonic probe manufacturing method

Disclosed are a sound damping component for ultrasonic probe, an ultrasonic probe, and an ultrasonic probe manufacturing method. Multiple through-holes (14A) penetrating a sound dampening body (13a) are formed with a drill, and conductive bodies (14) are formed in each of the through-holes (14A). Then, a first electrode unit (141) for connection to a piezoelectric element drive electrode is formed in each of the conductive bodies (14) on the entry side of the aforementioned drill. By this means, a sound dampening component, an ultrasonic probe and a manufacturing method thereof can be provided such that the piezoelectric element drive electrode can be connected to the signal line, which is on the drill entry side.
