    摘要: An acoustic wave device of the present application includes a piezoelectric substrate (14), interdigital transducer electrodes (13) formed on the piezoelectric substrate (14), and an SiO2 film (12) formed so as to cover the electrodes (13). The acoustic wave device also includes a displacement adjustment film (11) formed on the SiO2 film (12), and the displacement adjustment film (11) is formed from a substance whose acoustic velocity is slower than that of the substance forming the SiO2 film (12). According to this configuration, it is possible to suppress unnecessary waves as well as improve temperature characteristics. Also, by mounting such an acoustic wave device in a communication module or communication apparatus, it is possible to achieve an improvement in reliability.

    摘要: An angular velocity sensor is provided that includes a frame, an oscillator and torsion bars that connect the oscillator to the frame. The frame, the oscillator and the torsion bar are formed integral with each other by etching a material substrate in the thickness direction of the substrate. The oscillator, configured in the form of an H, includes a support, two first arms and two second arms. These arms extend from the support in an arm-extending direction perpendicular to the thickness direction of the substrate. The oscillator includes a mounting surface that is provided with a piezoelectric driver for generating in-plane oscillation of the oscillator, and with a piezoelectric detector for detecting out-of-plane oscillation of the oscillator.
