    Abstract: Provided is a PSA sheet that allows installation of a protection sheet with good shape precision on the surface of an object to be protected. The PSA sheet provided by this invention comprises a substrate whose primary component is a resin film and a PSA layer placed on one face of the substrate. The PSA sheet comprises a protection sheet part which is adhered to an adherend to protect it, a marginal part bounded from the protection sheet part by a tear-off line surrounding the protection sheet part, and a tear-aiding structure provided along the tear-off line. The PSA sheet is configured so that after the protection sheet part is adhered to the adherend, when the marginal part is pulled in a direction in which the PSA sheet is peeled off the adherend, the marginal part is torn off the protection sheet part.
