A terminal and a manufacturing method thereof includes: S1: providing a metal plate sheet, and punching the metal plate sheet to form a through slot thereon, such that the metal plate sheet forms two branches on two opposite sides of the through slot; S2: cutting one end of each of the two branches, such that the ends of the two branches are separated from each other to form two contact portions respectively, and a first distance is initially provided between the two contact portions; and S3: extruding at least one of the two branches, such that the extruded branch plastically deform to increase the first distance between the two contact portions to become a second distance, preventing the two contact portions of the terminal from contacting each other and moving altogether in the process where the terminal is pressed by the chip module and elastically deforms.
