PURPOSE: A method for manufacturing embedded materials for an automobile is provided to simply manufacture the embedded materials with preventing a harmful working environment. CONSTITUTION: A method for manufacturing embedded materials for an automobile includes the steps of obtaining materials formed by making a first polyestere fiber(20) having a first melting point as a core, covering the core with a second polyestere fiber(21) having a second melting point lower than the first melting point, and thereafter beating the unit fiber; preheating the materials between the first melting point and the second melting point; and cold pressure forming the preheated materials in a mold.
