PROBLEM TO BE SOLVED: To provide an ultraviolet curable pressure sensitive adhesive sheet which has good transmittance of ultraviolet rays, can reduce the adhesiveness of a pressure sensitive adhesive layer by ultraviolet irradiation, and simultaneously is colored to such an extent as to be discriminated by a sensor or the like. SOLUTION: The ultraviolet curable pressure sensitive adhesive sheet has an ultraviolet curable pressure sensitive adhesive layer laminated on a substrate film, and is colored to such an extent that the maximum value of the transmittance of rays having a wavelength of 300-400 nm comes to≥30% and, simultaneously, the minimum value of the transmittance of rays having a wavelength of 400-750nm comes to≤50%.
