PROBLEM TO BE SOLVED: To provide a circuit board having a terminal structure which enables reliable and easy connection with an electronic device or another circuit board, and also to provide an electrode lead structure of an electronic device using the circuit board. SOLUTION: In the circuit board, a conductor is cut into a pattern having a connection terminal for electrical connection with at least one of an electronic device and an external board, and surface protective layers 3 and 4 as insulating films are formed on both of front an rear surfaces of the circuit pattern. The surface protective layers have a notch wider than the connection terminal, in such a manner that one of the surface protective layers is provided on one of the front and rear surface of the connection terminal an the other is provided to expose the connection terminal. The electrode lead structure of an electronic device has opposed electrodes using the circuit board.
