▎ 摘　　要

NOVELTY - The probe (10) has a bonding layer (100), a sound absorbing layer (300) formed on the bonding layer, and a vibrator (200) present between the bonding layer and the sound absorbing layer. The sound-absorbing layer disperses heat generated in the bonding layer or the vibrator. The sound-absorbing layer includes a thermoplastic (310) and a thermally conductive filler (320). The sound-absorbing layer have a thermal conductivity of 5-25 W/mK and has an attenuation coefficient of 3-20dB/mm with respect to the ultrasonic waves generated by the vibrator. USE - Ultrasonic probe for receiving and graphicizing ultrasound reflected from inside of human body. ADVANTAGE - The degree of heat conduction of the bonding layer to the sound-absorbing layer is increased since the ultrasonic probe according to the present application uses a thermoplastic plastic and a thermally conductive filler as the sound-absorbing layer. when the ultrasonic probe is in operation, the temperature of the bonding layer is lower than the temperature of the bonding layer of the conventional ultrasound probe in operation, so that it can be in contact with the human body for a long time. The probe has a low surface temperature because heat can be well dispersed by the sound-absorbing layer. A higher voltage can be applied than that of a conventional ultrasound probe, and the strength of a signal received by the probe may be increased by the voltage, so that an ultrasound image is clear. Since the ultrasonic probe is manufactured by an injection process, the probe can be manufactured at a lower cost than a conventional ultrasonic probe, which is advantageous for mass production. Since the ultrasonic probe has a similar attenuation coefficient to that of the conventional ultrasonic probe, it is convenient to use and the performance can be maintained compared to the conventional ultrasonic probe.
