PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive sheet for a color cathode-ray tube which has a function of selectively absorbing the rays of the wavelengths except the three primary colors of red, blue, and green. SOLUTION: The pressure-sensitive adhesive sheet comprises at least one kind selected from inorganic acid salts and organic acid salts of rare earth metals, especially neodymium and erbium in its constituting materials and has a transmittance of the visible rays with wavelengths of blue, green, and red of >=40%, and exhibits a selective wavelength absorption for the visible rays with one or both wavelengths of 570 nm-590 nm and 500 nm-540 nm.
