PROBLEM TO BE SOLVED: To provide a surface-protective adhesive sheet for punching and drawing processing, which remarkably reduces the occurrence of the tear and ironing breakage of a surface-protective adhesive sheet when a metallic plate or the like to which the surface-protective adhesive sheet sticks is subjected to punching and drawing processing, especially to provide a surface-protective adhesive sheet for punching and drawing processing, which is effective for deep drawing.SOLUTION: A surface-protective adhesive sheet for punching and drawing processing is an adhesive sheet that has: a support layer consisting of a laminate of first and second non-oriented films; and an adhesive layer provided on one surface of the support layer, wherein storage elastic modulus G' in 1% distortion γ at 23°C, measured at a frequency of 0.016 Hz, in the adhesive layer is 3.0×105 or larger; and the amount of decrease in storage elastic modulus G', in 20% distortion γ based on the 1% distortion γ is 30% or lower. |
