    • PROBLEM TO BE SOLVED: To provide a light-shielding adhesive tape which is resistant to peeling between a light-shielding layer and an adhesive layer by repulsive force even under a high-temperature condition or a thermal cycling condition without using a halogen-containing vinyl chloride-vinyl acetate copolymer resin as a light-shielding layer and is excellent in reworkability. SOLUTION: In the light shielding adhesive tape, the light-shielding layer including a resin film and an ink layer and the adhesive layer are laminated, the halogen content of the light-shielding layer is 0.3 mass% or less, and an ink composition used in the light-shielding layer contains a polyester polyurethane resin, as the binder resin, in which peak temperature at tangent δ measured in dynamic viscoelasticity spectrum at a frequency of 1 Hz is -30 to 30°C. Since the light-shielding layer has adequate elasticity and stress relaxation by the light shielding self-adhesive tape containing an aliphatic isocyanate, alicyclic isocyanate or trimers thereof as a curing agent, the repulsive force is applied to the tape at a high temperature to inhibit separation and occurrence of cutting off is inhibited even if peeling it at a high speed in rework.
