PROBLEM TO BE SOLVED: To make an adhesive tape exhibit both a light shielding effect for an adherend and translucency during back light radiation.SOLUTION: A semitransparent light-shielding tape 10 includes a base material layer 20, a light-shielding layer 30 and an adhesive layer 40. The base material layer 20 is formed of a plastic material such as polyethylene terephthalate. The light-shielding layer 30 is laminated on one main surface of the base material layer 20. The light-shielding layer 30 is a black printed layer which is formed by printing, for example, black ink. The adhesive layer 40 is laminated on the other main surface of the base material layer 20. An acrylic polymer is suitably used as the adhesive layer 40. In the translucent light-shielding tape 10, transmittance for light with a wavelength of 550 nm is in the range of 0.010-10%. |
