Abstract
To provide an easily releasable adhesive film that can be easily released from an object, to which the film has been bonded, after processing and that does not deform or damage the object when released therefrom. This easily releasable adhesive film is configured by laminating, in the following order, a first film that is thermally shrinkable (a shrinkable film), an adhesive layer that contains a reactive oligomer together with an adhesive, a second film that is not thermally shrinkable (a non-shrinkable film), and an easily releasable adhesive layer. The reactive oligomer is contained in the adhesive layer in an amount of 12 to 130 parts by weight (inclusive) relative to 100 parts by weight of the adhesive. It is preferable that the easily releasable adhesive layer is configured as an easily releasable adhesive layer that is thermally curable/releasable and contains a reactive oligomer together with an adhesive. It is also preferable that the first film has a shrinkage of 50-90% (inclusive) in the main shrinkage direction at 120° C.
