PURPOSE: A front frame(100) reinforces rigidity thereof and impact energy absorbing performance by integrally composing a main frame and an auxiliary frame. CONSTITUTION: A front frame comprises a front frame main body and a front outer panel(130). The front frame body comprises a main frame(110) mainly absorbing impact load on collision from the longitudinal direction to the front side and an auxiliary frame(120) reinforcing the main frame(110) integrally manufactured. The front outer panel(130) is attached to the front frame main body. As the joining surface between the main frame(110) and the auxiliary frame(120) is removed and a reinforcing material can be easily inserted between the front frame main body and the frame outer panel(130), the rigidity is improved.
