Claims

[Scope of utility model registration request]

A sliding device having an insulating substrate, a conductive pattern formed on the insulating substrate and including a substantially arc-shaped resistor, and a contact point that is rotatably supported with respect to the insulating substrate and slides while contacting the conductive pattern. and a variable resistor configured such that a contact point of the slider can also slide over a region between both ends of the conductive pattern, wherein at least the region between both ends of the conductive pattern A variable resistor characterized in that a coating layer is formed on the insulating substrate so as to cover a portion on which the contact of the slider slides.
