This invention provides a separation method for an adhesive tape and a separation device that can reliably and efficiently perform the operation of removing the backing sheet from the adhesive sheet of the adhesive tape and can be automated with a simple structure. The adhesive tape comprises a base sheet, an adhesive sheet which is applied to the base sheet and a backing sheet laminated to the base sheet. According to the invention, one end of the adhesive tape is supported leaving that end as a free end. Separation means is used to bend the free end in the direction from a first surface of the adhesive tape to a second surface of the adhesive tape until slippage occurs between the adhesive sheet and backing sheet. While in this state, the separation means is withdrawn from the adhesive tape as it traces the end surface at the free end. Thus, the backing sheet is removed from the adhesive tape and can be affixed to an object.

[ What is claimed is:] [2.] A separation method for an adhesive tape, the adhesive tape including a base tape and a backing sheet laminated on the base tape, the base tape including a base sheet and an adhesive sheet which is sandwiched between the base sheet and the backing sheet, the base tape and the backing sheet having different friction coefficients on their end surfaces, the separation method separating the backing sheet from the base tape, the method comprising the steps of:supporting one end of the adhesive tape and leaving that end as a free end; andrubbing against the end surface of the free end with a separation means in a direction from one of the base and backing sheets with a lower friction coefficient toward one of the base and the backing sheets with a higher friction coefficient, wherein the step of rubbing is repeated a plurality of times.
