It will be. In that case, a support is attached to the back surface of the base material of the decorative pressure-sensitive adhesive sheet to form a laminated body, and the release sheet of the laminated body is peeled off to adhere to the adherend while the support is adhered. It is possible to prevent the base material layer from being deformed in accordance with the unevenness of the agent layer, and as a result, it is possible to retain the function of preferentially contacting only the uneven projections of the pressure-sensitive adhesive layer with the adherend surface. As a result, the initial adhesive strength can be similarly reduced.
