Abstract

A method of inspecting a sensor sheet formed by a roll-to-roll scheme for a touch sensor, the sensor sheet including a roll sheet and a sensor electrode layer thereon, the sensor electrode layer including sensor electrodes running in a prescribed direction, the sensor sheet further including a terminal connected to the sensor electrode layer and alignment marks, the method including: arranging the sensor sheet on an inspection table of an inspection device, the inspection table having an alignment mark and inspection electrodes running in another prescribed direction such that at least one of the alignment marks aligns with the alignment mark on the inspection table and such that the inspection electrodes face the sensor electrodes orthogonally in a plan view and are vertically separated by a dielectric to form capacitances at respective intersections therebetween; measuring the capacitances at the respective intersections; and outputting the measured capacitances as an inspection result.
