A circuit protection element and a circuit board with the circuit protection element are disclosed. The circuit protection element includes a metal base, and at least one opening slot located at the metal base. The metal base forms a positioning portion. One end of the metal base is fastened onto a circuit board. The bottom of the free end of the metal base contacts a conducting point located on the circuit board to make the circuit be in a conducting status. When the current is overloaded or the circuit is over-heated, the bottom of the free end of the metal base is heated so that the bottom of the free end of the metal base separates from the conducting point and the positioning portion is wedged with the circuit board. Thereby, the circuit becomes a broken circuit. The circuit protection element can prevent the electronic components from being burnt down.
