(57) [Abstract] [Purpose] To provide a double-sided adhesive tape having improved adhesiveness and peelability from an adherend due to generation of air bite, and a simple and inexpensive manufacturing method thereof. In the double-sided adhesive tape, an uneven surface is formed by embossing, and the height of the convex portion of the uneven surface is 20 to 2 The maximum width of the protrusions and the distance between the protrusions are On both sides of the base material in the range of 0.5 to 10 mm, A feature is that an adhesive layer having a thickness of 5 to 100 μm is provided. In addition, in the method for producing a double-sided adhesive tape, a pressure-sensitive adhesive having a viscosity adjusted to 100 to 20000 centipoise is directly applied to the base material. |
