(Thickness 0.8 mm) is adopted. Among the ethylene-vinyl acetate copolymer sheets, EVA is particularly excellent in moisture resistance. However, in order to closely seal the EL element 3, it must be heated to 160 ° C. or higher, and therefore, the protective sheet 11 of the EL element 3 may be impacted by heat. . In consideration of the same reason, the translucent substrate 1 is made of soda lime glass having excellent heat resistance.
