Patent ID: 8119332

Claim:
A method for manufacturing a coordinate detector having a resistive film formed on a substrate formed of an insulating material and a common electrode for applying a voltage to the resistive film, the substrate having a quadrangular shape, the method comprising the steps of: a) forming first resistive film removal regions by removing predetermined first regions of the resistive film provided along a peripheral edge of the substrate; b) forming the common electrode on the first resistive film removal regions; c) applying voltage to the resistive film; d) measuring an electric potential of the resistive film; e) calculating second resistive film removal region data according to the measured electric potential; and f) forming second resistive film removal regions by irradiating a laser beam to predetermined second regions of the resistive film according to the calculated second resistive film removal region data; wherein the step d) is performed between the step a) and the step f).
