Glass article and electronic device

Abstract

A glass article includes a glass plate having a hole in a surface and a glass block that fills the hole in the glass plate. The glass plate is formed of a first glass material, and the glass block is formed of a second glass material having a different composition from the first glass material. A glass transition point (Tg1) of the first glass material is higher than a glass transition point (Tg2) of the second glass material. An absolute value (ΔCTE=|CTE1−CTE2|) of a difference between an average coefficient of linear expansion (CTE1) of the first glass material and an average coefficient of linear expansion (CTE2) of the second glass material is less than 35.8×10−7/° C.
