Abstract
A method of manufacturing a coordinate detector having a resistive film and a common electrode for applying a voltage to the resistive film is disclosed that includes the steps of (a) applying a photoresist onto the resistive film formed on a substrate formed of an insulator; (b) forming a resist pattern on the resistive film by exposing the applied photoresist to light through a predetermined mask and subsequently developing the applied photoresist; (c) forming a resistive film removal region by removing a portion of the resistive film without the resist pattern; (d) removing the resist pattern after step (c); and (e) forming the common electrode over the resistive film removal region after step (d).

A method of manufacturing a coordinate detector having a resistive film and a common electrode for applying a voltage to the resistive film, the method comprising:
- printing an etching paste on a portion of the resistive film formed on a substrate formed of an insulator, the portion being to be removed to form a resistive film removal region;
- removing the portion of the resistive film with the etching paste by heat treatment;
- removing the remaining etching paste after the heat treatment;
- and
- forming the common electrode over the resistive film removal region.
