Document Type and Number:
Japanese Patent JP4428609
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a highly reliable touch panel with a driving electrode having a less dispersed resistance value. SOLUTION: The resistance film type analog touch panel comprises a transparent electrode formed on an upper board and a transparent electrode formed on a lower board, both of which are opposed to each other in spaced relation, and the driving electrode connected to the transparent electrodes. The driving electrode is formed with a fired film of conductive paste consisting of a 30-45 wt.% silver powder 32 and 15-25 wt.% insulating auxiliary particles 30 mixed in a resin solution. The particle size of the silver powder 32 is within a range of 0.1-5 μm, and the insulating auxiliary particles 30 are plastic balls, ceramic balls or glass balls with their average particle size being within a range of 1-20 μm and satisfied with the conditions of 3-10 times the particle size of the silver powder 32.
