A resistor pattern of an insulating substrate is printed with reference to a first contact portion and a second contact portion, and the insulating substrate is attached to a holder such the first and second contact portions of the insulating substrate are brought into contact with second contact portions of the holder to position the insulating substrate. Therefore, an error between the relative positions of a slider piece and a resistor pattern is decreased, and variations in resistance change characteristic are decreased.
