Claim:
1. A method of producing an impact-absorbing pressure-sensitive adhesive sheet, the method comprising: providing an impact-absorbing pressure-sensitive adhesive layer having therein an impact-absorbing layer, the impact-absorbing pressure-sensitive adhesive layer being formed on one side of a substrate; irradiating the impact-absorbing pressure-sensitive adhesive layer with laser light for cutting so as to form a fully-cut edge of the impact-absorbing pressure-sensitive adhesive layer on the substrate such that the layer becomes separable from the fully-cut edge from the substrate, wherein: a cut surface of said cut edge of the impact-absorbing pressure-sensitive adhesive layer includes a tapered surface; and the tapered surface has a taper angle of 65° or more.
