Abstract
A touch panel glass substrate which can be manufactured simultaneously with other touch panel glass substrates, is free of microcracks in edges, and has predetermined strength, and a method for manufacturing the same are provided. An original glass plate as large as to cut out a plurality of glass substrates is prepared. Detection electrode traces and lead wiring traces on each glass substrate are simultaneously formed on the original glass plate. The original glass plate is then chemically etched to separate the touch panel glass substrates. The separation by chemical etching produces no microcracks in edges.
