PURPOSE:To obtain a pressure-sensitive adhesive sheet simply at a low cost, which has excellent sticking workability in registration and gives a good surface profile after bonding, by using a pressure-sensitive adhesive layer obtd. by forming a specified difficultly sticking solid layer on at least one surface of a flat pressure-sensitive adhesive layer. CONSTITUTION:This pressure-sensitive adhesive layer is obtd. by forming a difficultly sticking solid layer 2 thinner than a flat pressure-sensitive adhesive layer 1 on at least one surface or surface layer of said adhesive layer 1, said solid layer 2 being formed by coating said adhesive layer 1 directly or indirectly with a solidifiable flow material and then solidifying said material. A base material layer 3 is provided on one side of the adhesive layer 1 of the pressure- sensitive adhesive to obtain a pressure-sensitive adhesive sheet. The adhesive sheet is stuck on a substrate by sticking the sheet on the surface of a substrate 5 to be stuck, registering positions to be stuck and bonding them from the back of the base layer 3 under pressure.
