The present invention relates to a lightweight cowl cross member for a vehicle. The lightweight cowl cross member for the vehicle of the present invention comprises: a main assembly formed by injecting certain parts into a main pipe; and a sub-assembly which is made smaller than the main pipe and is formed by injecting some parts. Each of the main pipe and a sub pipe includes: a standard thickness wall part formed to a predetermined thickness; a strength reinforcing wall part which is connected to the standard thickness wall part and is formed thicker in an overlaid form than the wall body thickness of the standard thickness wall part to enhance strength; and an undercut for resin filling which is provided on at least one side of the standard thickness wall part or the strength reinforcing wall part to prevent deformation caused by injection pressure as the injection resin fills. Therefore, the lightweight cowl cross member for the vehicle can maintain the performance of components and achieving weight reduction.
