A streamline shape accessory of a mobile phone coupling loop and a manufacturing method for the same are provided to prevent deterioration of productivity resulting from errors of forming by forming an aluminum linear material in a compressing method. The manufacturing method of a streamline shape accessory of a mobile phone coupling loop includes the steps of: a preparation step(S1) of extruding aluminum material into a linear material; a crush-forming step(S2) of forming and cutting a streamline shape head portion by crushing one end of the linear material into a mold; a pressing step(S3) of processing a loop recess by injecting the other end of the component obtained from the crush-forming step(S2) into a mold; buffing/barrel step(S4) of grinding corners of components; an anodizing step(S5) of forming an oxide film on the surface of the components; and an inspecting/forwarding step(S6).
