The invention discloses a circuit board and a method for forming a connection part thereof. The circuit board comprises a connection part provided with metal sheets. The method for forming the connection part comprises the following steps of: coating metal paste on the metal sheet in a screen printing manner to form a plurality of paste-shaped points on the metal sheet; and then curing the plurality of paste-shaped points to form a plurality of metal points, wherein the inoxidizability of the plurality of metal points is superior to that of the metal sheet. Thus, the circuit board can electrically contact external electric elements through the metal points with better inoxidizability without the oxidizing the metal sheet. In addition, the controllable planeness of the contact plane can beobtained by arranging a plurality of metal points on the metal sheet, and the problem that the metal sheet is coated with other materials to destroy the planeness of the contact plane is avoided.
