The present invention relates to a backing block for an ultrasonic probe and to a method for manufacturing same. The method for manufacturing the backing block for an ultrasonic probe according to the present invention includes: a filling step for filling a backing block body which has an inner space where an open section is formed on one side with a sound absorbing material and a compression step for compressing the sound absorbing material with which the backing block body is filled. According to the present invention, the sound absorbing material can be introduced in large quantity, and ultrasonic waves transmitted from a piezoelectric ceramic to the backing block can be absorbed effectively so that further improved acoustic characteristics can be provided.Cette invention concerne un bloc-renfort pour sonde ultrasonore et sa méthode de fabrication. La méthode de fabrication de linvention consiste à remplir un corps de bloc-renfort comportant un espace interne à section latérale ouverte avec une matière absorbant les sons, puis à comprimer ladite matière absorbant les sons. Selon linvention, la matière absorbant les sons peut être introduite en quantité importante, et les ondes ultrasonores transmises par une céramique piézoélectrique au bloc-renfort peuvent être absorbées efficacement et améliorer ainsi les caractéristiques acoustiques.본 발명은 초음파 프로브용 후면블록 및 그의 제조방법에 관한 것으로서, 본 발명의 초음파 프로브용 후면블록 제조방법은, 한쪽에 개방부가 형성된 내부공간을 가지는 후면블록본체(backing block body)의 내부에 흡음재(sound absorbing material)를 충진하는 충진단계 및 후면블록본체에 충진된 상기 흡음재를 압착하는 압착단계를 포함한다. 이를 통해 흡음재의 대량 투입이 가능하게 되어, 압전 세라믹에서 후면블록으로 전파되는 초음파를 효과적으로 흡수하여 더욱 향상된 음향 특성을 제공할 수 있다.
