A probe of an ultrasonic imaging apparatus and a method for manufacturing the same are disclosed. The probe for an ultrasonic imaging apparatus includes a piezoelectric unit including a piezoelectric substance and an electrode; a printed circuit board (PCB) unit having a printed circuit board (PCB), configured to be formed at a lateral surface of the piezoelectric unit; a matching layer formed at front surfaces of the piezoelectric unit and the PCB unit; and a backing layer formed at a back surface of the piezoelectric unit and the PCB unit. The probe and a method for manufacturing the probe can reduce a variation of ultrasonic acoustic characteristics caused by a printed circuit board (PCB) because the PCB is not arranged among a piezoelectric substance, a matching layer, and a backing layer. A PCB is provided at a lateral surface of the piezoelectric substance, so that strength against impact can be increased either during channel division based on dicing or during the usage time of a probe. In addition, a single crystal (monocrystal) may be used as a piezoelectric substance or the like, such that a probe having a large bandwidth can be formed, and low-frequency ultrasonic signals and high-frequency ultrasonic signals can be transmitted and received. In addition, the probe and the method for manufacturing the same can easily perform channel division of the acoustic module, and make the divided acoustic module using a curvature, and thus can be applied to various technical fields without being limited to the shapes of probes. |
