Patent number: 9663396Abstract: A glass sheet has one surface and the other surface facing the one surface in a thickness direction, wherein a fluorine concentration (average fluorine concentration by SIMS at a depth of 1 to 24 ?m) in the one surface is higher than that in the other surface. The following expression is satisfied: 0.07??F/?H2O. ?F (mol %) is a value obtained by subtracting an average fluorine concentration in the surface having the lower fluorine concentration from that in the surface having the higher fluorine concentration, and ?H2O (mol %) is an absolute value of a value obtained by subtracting an average H2O concentration in the surface having the higher fluorine concentration from that in the surface having the lower fluorine concentration.Type: GrantFiled: September 26, 2014Date of Patent: May 30, 2017Assignee: ASAHI GLASS COMPANY, LIMITEDInventors: Satoshi Miyasaka, Hideko Nakada, Yasuo Hayashi, Makoto Fukawa, Toshifumi Nihei, Masanobu Shirai, Naoki Okahata, Koji Nakagawa, Kazuhiko Yamanaka, Kunio Watanabe, Shiro Tanii, Nobuaki Ikawa, Daisuke Kobayashi, Junichi Miyashita, Ryosuke Kato
