The present invention relates to a heat-releasing sheet and a preparing method thereof. The heat-releasing sheet includes: a filler having an iron oxide; a silicone resin; and a mattress including at least one crosslinking agent selected from a group consisting of poly-hydrogen-siloxane-based and organic-peroxidation-based crosslinking agents. The preparing method of the heat-releasing sheet includes the steps of: mixing the iron oxide, the silicone resin, and the crosslinking agent to form a complex, and crosslinking and hardening the complex. According to the present invention, it is possible to use the iron oxide without a separate process and to acquire excellent heating performance. 본 발명은 방열 시트 및 이의 제조방법에 관한 것으로, 보다 상세하게는 산화철을 포함하는 충진제; 실리콘 수지; 및 폴리하이드로젠실록산계 및 유기과산화물계 가교제로 이루어진 그룹으로부터 선택된 적어도 하나의 가교제를 포함하는 매트리스를 포함하는 방열 시트; 및 산화철, 실리콘 수지 및 상기 가교제를 혼합하여 복합체를 형성하는 단계, 및 상기 복합체를 가교 및 경화하는 단계를 포함하는 방열 시트의 제조방법에 관한 것으로, 본 발명에 의하면, 산화철을 별도의 공정 없이 이용할 수 있으며 우수한 발열 성능을 획득할 수 있다.
