We propose an educational tool for foundation of electricity using conductive pens. Electrical leads for an experiment were drawn on the inkjet printing paper using silver ink marker. Electrical resistances were drawn by two kinds of pens; one was the same silver ink marker and the other was a carbon ink brush pen. A combined resistance was measured and compared with the calculated value. The relative error was less than ±1% in both series and parallel connection with the resistances drawn by the carbon ink brush. Therefore, this is useful to experience and learn the foundation of electricity.
