An apparatus for manufacturing a bracket-integrated double-layer door impact beam is provided. The apparatus includes a lower mold having a lower cavity formed with a base material molded to have a “U”-shaped cross section and a predetermined length. The base material is seated on the lower cavity. A lower electrode terminal is disposed in the lower mold to contact the base material. An upper mold has an upper cavity therein and is coupled with the lower mold to pressurize both end portions of the “U”-shaped cross section of the base material inward to form the base material with an “O”-shaped cross section. An upper electrode terminal is disposed in the upper mold to contact the base material.
