A headlining having a heat shielding function for a vehicle and a manufacturing method for producing the headlining, where a complex layer formed of glass fiber and polypropylene is manufactured among various layers forming the headlining having a multilayered structure, and a hot melt film containing a heat shielding material is further provided on at least one of both surfaces of the complex layer to shield heat by the headlining. In so doing, the headlining is capable of reducing an internal temperature of the vehicle even in the summertime, and thus an operation time of an air conditioner is reduced, and fuel efficiency of the vehicle is increased. The headlining also has a heat shielding function for a vehicle, in which carbon nanotubes as the heat shielding material are used to provide the heat shielding and weight lighting effects and also to simultaneously improve the fuel efficiency of the vehicle.
