The present invention relates to a foam-integrated injection molding structure including an electroluminescence (EL) sheet, which comprises an EL sheet including: a substrate; a light-emitting EL sheet disposed on the upper side of the substrate; a foam layer disposed on the upper side of the EL sheet and containing an additive for preventing exposure of the substrate or the EL sheet when the EL sheet does not emit light; and a skin layer disposed on the upper side of the foam layer. According to the present invention, by providing the EL sheet in a vehicle interior material, an interior effect can be raised by emitting light at a predetermined portion inside a vehicle.

    본 발명은 이엘 시트를 포함한 발포 일체 사출성형 구조에 관한 것으로, 기재; 상기 기재의 상측에 배치되는 발광 가능한 이엘 시트(EL(Electro luminescence) sheet); 상기 이엘 시트의 상측에 배치되는 발포 형성되고, 상기 이엘 시트의 비발광시 상기 기재 또는 상기 이엘 시트의 노출을 방지하는 첨가물을 포함하는 발포층; 및 상기 발포층의 상측에 배치되는 스킨층을 포함하는, 이엘 시트를 포함한다.
