Summary:PURPOSE: An Adhesive tape without a base film is provided to easily remove a heavy-separation and a soft-separation release film by optimizing a separation force between the heavy-separation and the soft-separation release film. CONSTITUTION: An Adhesive tape without a base film comprises a soft-separation release film (10) which has a base film (11) and a release layer (12); a heavy-separation release film (20) which has a base film (21) and a release layer (22); and an adhesive layer (30) formed between the soft-separation release film and the heavy-separation release film. The separation force of the soft-separation release film is 1-3 g/25mm. The separation force of the heavy-separation release film is 3-9 g/25mm and satisfies a condition: P2/P1=1.3-3.0 where P1 is the separation force of the soft-separation release film and P2 is the separation force of the heavy-separation release film.
