ABSTRACT:
A method of manufacturing a stator for a variable resistor comprises a step of preparing a heat resistant film, a step of providing a resistor film on the heat resistant film, a step of obtaining a transfer sheet by treating the resistor film provided on the heat resistant film with a silane coupling agent, a step of preparing a forming die having a cavity for forming a substrate, a step of locating the transfer sheet in the forming die to expose at least a part of the resistor film in the cavity, a step of introducing resin into the cavity to form a substrate joined with at least a part of the resistor film and a step of separating the heat resistant film from the substrate to leave the resistor film.
