Provided are a polarizing plate in which the decline in single transmittance in a high-temperature environment is suppressed, and an easy adhesive film used therefor. An easy adhesive film (1) is provided with an easy adhesive layer (15) on the surface of a transparent film substrate (11). The easy adhesive layer contains a binder resin and a water-soluble radical scavenger. The polarizing plate (50) has a configuration in which the easy adhesive film (1) is bonded to at least one side of a polyvinyl alcohol-based polarizer (5) through an adhesive layer (6). 고온 환경하에서의 단체 투과율의 저하가 억제된 편광판 및 그것에 사용되는 이접착 필름을 제공한다. 이접착 필름(1)은 투명 필름 기재(11)의 표면에 이접착층(15)을 구비한다. 이접착층은 바인더 수지 및 수용성의 라디칼 포착제를 포함한다. 편광판(50)은 폴리비닐알코올계 편광자(5)의 적어도 일방의 면에 접착제층(6)을 통해 상기 이접착 필름(1)이 접합된 구성을 갖는다.
