Title (EN) ACOUSTIC WAVE ELEMENT AND COMMUNICATION DEVICE
(FR) ÉLÉMENT À ONDES ACOUSTIQUES ET DISPOSITIF DE COMMUNICATION
(JA) 弾性波素子および通信装置
Abstract:
(EN) This invention is provided with: a piezoelectric substrate 7 having a first surface 7a and a second surface 7b; an electrode part 5 disposed on the first surface 7a, the electrode part 5 exciting an acoustic wave; and a support substrate 9 joined to the second surface 7b of the piezoelectric substrate 7, the support substrate 9 comprising a material having a smaller linear expansion coefficient than the material constituting the piezoelectric substrate 7. The electrode part 5 comprises a first region and a second region oriented in a two directions, comprising a first direction and a second direction, displaced from the normal of the first surface 7a.
(FR) Le dispositif selon l'invention comprend : un substrat piézoélectrique (7) présentant une première surface (7a) et une seconde surface (7b) ; une partie d'électrode (5) disposée sur la première surface (7a), la partie d'électrode (5) excitant une onde acoustique ; et un substrat de support (9) relié à la seconde surface (7b) du substrat piézoélectrique (7), le substrat de support (9) comprenant un matériau ayant un coefficient d'expansion linéaire inférieur à celui du matériau constituant le substrat piézoélectrique (7). La partie d'électrode (5) comprend une première région et une seconde région orientées dans deux directions, comprenant une première et une seconde direction, décalée par rapport à la normale à la première surface (7a).
(JA) 第1面7aと第2面7bとを有する圧電基板7と、第1面7aに配置された、弾性波を励振する電極部5と、圧電基板7の第2面7bに接合されるとともに、圧電基板7を構成する材料に比べて線膨張係数の小さい材料からなる支持基板9と、を備え、電極部5は、第1面7aの法線からずれた第1方向および第2方向の2方向に配向している第1領域および第2領域からなる。
