The present invention relates to a terminal protecting tape (1) used in a step for forming an electromagnetic-wave blocking film on a terminal-attached semiconductor device. The terminal protecting tape (1) has a viscoelastic layer (12). In a dynamic viscoelasticity measurement of the viscoelastic layer (12), the value of tanδ at 50°C is 0.2 or more, and the thickness of the viscoelastic layer (12) is 80-800 μm. |
