SHEET GLASS, CRACK DETECTION SYSTEM FOR GLASS, AND DEVICE AND METHOD FOR TRANSMITTING INFORMATION ABOUT GLASS CRACK

摘要

PROBLEM TO BE SOLVED: To provide a concrete means for certainly detecting a crack when providing a conductor film on a sheet glass configured as laminated glass.;SOLUTION: This sheet glass 1 has: a first sheet glass 3 consisting of a substrate formed as tempered glass; a second sheet glass 12 disposed opposite to the first sheet glass at a prescribed interval; an intermediate film 14 sandwiched by the first sheet glass 3 and the second sheet glass 12; the conductor thin film 4 formed on a face of the first sheet glass 3 on the intermediate film 14 side; and a pair of electrode parts 5a, 5b disposed on the conductor thin film 4 at a prescribed interval close to each other. The second sheet glass 12 is set as raw sheet glass, a part on the first sheet glass 3 is set as a non-laminated part 30 wherein the intermediate film 14 is not locally present, and the pair of electrode parts 5a, 5b are provided inside the single non-laminated part 30.;COPYRIGHT: (C)2005,JPO&NCIPI
