In a method of resistance adjustment, a resistance adjusting element and a resistance adjusting device, in order to readily recognize a terminal end of a cut-off part for connecting cut-off parts when a resistance film is cut off at several times and to prevent a resistance value from changing due to cracking of the resistance film, the resistance adjustment having preliminary resistance adjustment carried out before an electronic circuit board is incorporated in the associated equipment, and final resistance adjustment which is carried out after the electronic circuit board is incorporated in the associated equipment, the preliminary resistance adjustment forming a first cut-off part in the resistance film and forming a second cut-off part serving as a marker in the resistance film, so as to be connected to the first cut-off part substantially at a position of one end of the first cut-off part, and the final resistance adjustment recognizing the position of the second cut-off part, and forming the third cut-off part in the resistance film in a direction different from the cutting off direction of the second cut-off part while leaving a length in the resistance film capable of preventing cracking of the resistance film.
