Claims

[Claims for Utility Model Registration] (1) A resistive film with which the contact piece of the slider comes into contact is provided on the substrate, a hole is provided that penetrates the electrode film at the end of this resistive film and the substrate, and the inner surface of this hole is A variable resistor in which an electrode layer is formed next to the electrode film, and a shaft portion provided on a separate metal terminal is press-fitted into the hole to press the outer periphery of the shaft portion to the conductive layer. (2) Utility model registration claim 1, characterized in that the electrode film and the electrode layer in the hole are made of the same material as the resistive film.
Variable resistor as described in section. (3) The variable resistor according to claim 1, wherein the electrode film and the conductive layer in the hole are resistive films having a small resistance value. (4) Utility model registration claim 1, characterized in that the electrode film and the conductive layer in the hole are made of a metal film such as silver.
