The present invention relates to a headliner basic material for vehicles comprising: a first non-woven fabric layer; a first inorganic fiber mat layer; a polyester resin foamed sheet layer; a second inorganic fiber mat layer; and a second non-woven fabric layer which are sequentially layered. A glass shop is dispersed between the first non-woven fabric layer and the first inorganic fiber mat layer and between the second non-woven fabric layer and the second inorganic fiber mat layer. The headliner basic material for vehicles has excellent durability, bending strength and bending elastic modulus.
