The present invention relates to a dash insulation pad for a vehicle, comprising a first absorption layer, a sound insulation layer, an electromagnetic shielding film, and a second absorption layer. The present invention shields electromagnetic waves emitted from an electronic component mounted on an engine room or electromagnetic waves which may be emitted to an inner side of a vehicle from an outer side of the vehicle through the engine room by using the dash insulation pad, and thus the electromagnetic waves can be safely shielded by the light dash insulation pad and any failure and malfunction can be prevented from occurring around other electronic devices due to the electromagnetic waves, thereby promoting a safe operation, minimizing damage to a body of a driver or a passenger, and making a safe and fresh indoor environment. Especially, in the present invention, a metal which has excellent electromagnetic shielding properties and weight reducing difficulties is deposited to improve weight-lightening and electromagnetic shielding efficiency, and attachment is performed by using an adhesive layer made of a conductive material having more excellent light weight characteristics, flexibility, and workability than the metal, thereby increasing weight-lightening efficiency of the dash insulation pad and electronic device shielding efficiency.

    본 발명은 엔진룸에 장착한 전자 부품에서 방출한 전자기파나 자동차 외부에서 엔진룸을 통해 실내로 투과할 우려가 있는 전자기파를 대시 인슐레이션 패드를 통해 차폐하므로 가벼우면서 안전하게 전자기파를 차폐하여 전자기파가 주변의 다른 전자기기에 장애나 오작동 등을 일으키는 것을 방지하여 안전운행을 도모할 뿐만 아니라 운전자나 탑승자의 인체에 해를 가하는 것을 최소화하여 안전하고 쾌적한 실내 환경을 조성할 수 있다. 특히, 본 발명은 전자파 차폐가 우수하나 경량화에 어려움이 있는 금속을 증착하여 경량화와 전자파 차폐 효과를 높이면서도 금속보다 경량성과 유연성 그리고 가공성이 우수한 도전성 재질의 접착층을 이용하여 접착하므로, 대시 인슐레이션 패드의 중량 경량화와 더불어 전자기 차폐 효과를 높일 수 있다.
