PURPOSE: A heat fusion device is provided to prevent a fused part from being deformed due to stress by minimizing repelling power through a stress dispersing unit. CONSTITUTION: A heat fusion device comprises a jig(20), a heat fusion tool(30), and a stress dispersing unit(40). Components(10,11) are overlapped with each other and are placed on the jig. The heat fusion tool heats and presses the placed components. During the heat fusion process of the heat fusion tool, the stress dispersing unit minimizes stress generated in a fused part(15).
