This invention provides a laminate for a luminescent element that can be used as a protecting material for the body of luminescent elements, for example, substrates and sealing vessels for luminescent elements such as organic EL elements, is transparent, and has both a gas barrier function and a deoxygenating function. There is also provided a luminescent element comprising this laminate for a luminescent element as a substrate and/or a sealing vessel. The laminate for a luminescent element is characterized by stacking an oxygen absorbing layer ( 3 ) containing a conjugated diene polymer cyclized product having a percentage unsaturated bond reduction of not less than 10% and a gas barrier layer ( 1 ). Preferably, the laminate for a luminescent element has such properties that the oxygen absorption of the conjugated diene polymer cyclized product is not less than 5 mL/g, the rate of oxygen absorption from the surface of the oxygen absorption layer is not less than 1 mL/m<SUP>2</SUP>/day, the coefficient of oxygen permeability of the gas barrier layer is not more than 5.0 mL/m<SUP>2</SUP>/day, and the light transmittance in a wavelength region of 400 nm to 650 nm is not less than 85%. |
