Disclosed is a method for manufacturing a polyimide composite sheet. The method for manufacturing a polyimide composite sheet comprises the following steps: performing a corona treatment and a first flame treatment on a polyimide film; applying an adhesive on the corona treated and first flame treated polyimide film; performing a second flame treatment on a silicon sheet; and stacking and compressing the second flame treated silicon sheet on the polyimide film coated with the adhesive so that the second flame treated surface faces the surface coated with the adhesive. The polyimide composite sheet prepared by the method of the present invention can be repeatedly compressed and no foreign matter remains or is torn after the compression. In addition, the winding phenomenon and the separation phenomenon do not appear. 폴리이미드 복합시트의 제조 방법이 개시된다.
