Document Type and Number:

Japanese Patent JP6633544

Kind Code:

B2

Abstract:

Provided is a surface acoustic wave device using a novel and steadily suppliable piezoelectric material that is resistant to a high-temperature environment and enables the surface acoustic wave device to use a 2 GHz to 2.5 GHz band or higher. The surface acoustic wave device includes: a piezoelectric substrate formed from a monocrystal of gehlenite (CAS: Ca2Al(AlSi)O7); and interdigital transducers formed on a surface acoustic wave propagation plane of the piezoelectric substrate.
