Provided is a cast-coated pressure-sensitive adhesive sheet which hardly causes a curling trouble after ink jet recording which comprises a cast-coated recording paper, a pressure-sensitive adhesive layer and a release coated paper laminated via the pressure-sensitive adhesive layer on the side opposite to the recording layer, with the adhesive sheet having a difference between the two characteristic values (A) and (B) within the range of 0.00 to 0.10%, expressed in absolute value, wherein the characteristic value (A) is an irreversible shrinkage factor of the cast-coated recording paper in the CD direction determined under an environment that the relative humidity thereof is raised to 90% from 35% and then lowered to 35% and the characteristic value (B) is a shrinking rate of the release coated paper in the CD direction determined under a condition that the relaltive humidity of the environment is changed from 75% to 60% in the course of lowering the relative humidity from 90% to 35%.
