Abstract
A cover glass () includes a glass layer (), a viscoelastic layer (), and an acoustic impedance adjusting layer () disposed between the glass layer () and the viscoelastic layer (). When acoustic impedance of the glass layer () is Zg, acoustic impedance of the acoustic impedance adjusting layer () is Zm, and acoustic impedance of the viscoelastic layer () is Zd, the cover glass () satisfies a relationship of Zg>Zm>Zd.
