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.
