An electromagnetic handwriting pen includes a casing unit, an ink writing unit and an electromagnetic writing unit. The ink writing unit is disposed inside the casing unit and includes an ink pen core having a pen nib. The electromagnetic writing unit is disposed inside the casing unit and includes a circuit substrate far away from the pen nib, an electricity conducting element adjacent to the circuit substrate, an elastic element insulatively disposed between the circuit substrate and the electricity conducting element, and a magnetic structure adjacent to the pen nib and electrically connected to the circuit substrate. The circuit substrate has at least two electrode portions adjacent to and facing the electricity conducting element. Whereby, when the electricity conducting element is moved to concurrently contact the at least two electrode portions, the at least two electrode portions are electrically connected with each other through the electricity conducting element.
