Provided are a gettering agent, an absorptive film including the same, and an organic electronic device. In detail, the absorptive film including the gettering agent of the present application is provided on the front side and/or back side of the organic electronic device, and effectively absorbs and blocks moisture, thereby improving the lifespan and durability of the organic electronic device. In addition, the gettering agent of the present application uses a moisture absorbent particle having a nano size to secure transparency of the absorptive film, thereby implementing a top emitting device and also absorbing moisture in the atmosphere during the manufacturing process. Therefore, it is possible to solve the problem of losing the total amount of moisture absorption.
