Disclosed are a boron nitride-based heat-radiating filler having enhanced vertical thermal conductivity, a heat-radiating sheet, and a manufacturing method therefor. A heat-radiating filler according to an embodiment of the present invention is formed by the fusion of hexagonal boron nitride (h-BN) onto the surface of wire-type millimeter-length glass fibers through a binder. L'invention concerne une charge de rayonnement de chaleur à base de nitrure de bore ayant une conductivité thermique verticale améliorée, une feuille de rayonnement de chaleur et leur procédé de fabrication. Une charge de rayonnement de chaleur selon un mode de réalisation de la présente invention est formée par la fusion de nitrure de bore hexagonal (h-BN) sur la surface de fibres de verre de longueur millimétrique de type fil par l'intermédiaire d'un liant. 수직 열전도도를 향상시킨 질화붕소 기반 방열 필러, 방열 시트 및 그 제조방법이 개시된다. 본 발명의 일 실시예에 따른 방열 필러는 mm급 길이를 갖는 와이어 형태의 유리 섬유 표면에 육방정 질화붕소(h-BN)가 바인더를 통해 융착되어 형성된다.
