The present invention relates to a ferrite composite material for a current detection light sensor having an electromagnetic wave shielding effect. More specifically, the present invention relates to the ferrite composite material for the current detection light sensor having the electromagnetic wave shielding effect that can be applied to a fiber of the current detection light sensor by comprising a metal ferrite particle having an electro magnetic susceptibility (EMS) and magnetic flux density and a high conductivity material having an electro magnetic interference (EMI) effect. Therefore, the present invention is capable of reducing a noise of a communication signal. 본 발명은 전자기파 차폐 효과를 갖는 전류 감지 광 센서용 페라이트 복합소재에 관한 것으로, 보다 구체적으로 전자기 내성(Electro Magnetic Susceptibility, EMS) 및 자속 밀도를 갖는 금속 페라이트 입자 및 전자기파 차폐(Electro Magnetic Interference, EMI) 효과를 갖는 고전도성 소재를 포함하여 전류 감지 광 센서의 파이버에 적용 가능한 전자기파 차폐 효과를 갖는 전류 감지 광 센서용 페라이트 복합소재에 관한 것이다.
