Zusammenfassung:	Disclosed is a back-protective sheet for a solar cell module which has an improved reflection efficiency with respect to the light of a specific area including a near infrared ray. The back-protective sheet comprises: a first resin layer including three kinds of inorganic pigments having 50% or greater reflection efficiency in a specific area of an infrared ray among inorganic pigments; a second resin layer laminated at the bottom of the first resin layer and reflecting the light penetrating through the first resin layer; and a third resin layer laminated at the bottom of the second resin layer and reflecting the light penetrating through the second resin layer. 근적외선을 포함한 특정 영역의 광에 대한 반사율을 향상시킨 태양전지모듈용 이면보호시트가 개시된다. 이면보호시트는, 무기안료들 중에서 적외선 영역의 특정 영역에서의 반사율이 50% 이상인 3종의 무기안료들을 포함하는 제1 수지층, 제1 수지층 하부에 적층되며 제1 수지층을 투과하는 광을 반사하는 제2 수지층, 및 제2 수지층 하부에 적층되며 제2 수지층을 투과하는 광을 반사하는 제3 수지층을 포함한다.
