The present invention relates to a manufacturing method of a metal printed circuit board (PCB) assembly for a vehicle lamp, and an assembly. The manufacturing method of a metal PCB assembly for a vehicle lamp comprises the following steps: (S100) preparing a material of a metal PCB (14); (S110) forming a circuit pattern (22) and a plurality of unit patterns (16) in the material of the metal PCB (14), and cutting the same to form the metal PCB (14); (120) forming a bent groove (24) on a lower side of the metal PCB (14); (S130) protruding each unit pattern (16) forward around the bent groove (24) of the metal PCB (14) to make each unit pattern (16) inclined; and (S140) combining a step type injection-molded product (12) while the unit patterns (16) protrude. |
