In the present document, disclosed is a method for easily manufacturing an insulation pad embedded with a magnet. The method for manufacturing an insulation pad according to an embodiment comprises the steps of: preparing a sheet-shaped substrate; performing hot press forming on the substrate, to form a pad shape with grooves on the substrate; inserting, into the groove, a magnet with double-sided tape attached to a side facing the groove; attaching non-woven tape to the substrate, to close the groove; and performing cold press forming on the substrate. 본 문건은 마그네틱이 내장된 인슐레이션 패드를 용이하게 제조할 수 있는 방법을 개시한다. 실시예에 따른 인슐레이션 패드 제조방법은, 시트 형태의 기재를 준비하는 단계; 상기 기재를 열간 프레스 성형하여, 상기 기재에 홈이 구비된 패드의 형상을 형성시키는 단계; 상기 홈과 마주하는 면에 양면테이프가 부착된 마그네틱을 상기 홈에 삽입하는 단계; 상기 기재에 부직포테이프를 부착하여, 상기 홈을 폐쇄하는 단계; 및 상기 기재를 냉간 프레스 성형하는 단계;를 포함한다.
