摘要： A vibration power generating device includes a first substrate and a second substrate, a first electrode formed on the first substrate, a fixed structural body, elastic structural bodies which connect the first substrate and the fixed structural body with each other, and a second electrode formed on the second substrate. Since the overlapping area of the electrodes is increased by arranging rectangular or square conductor parts of the first electrode and rectangular or square conductor parts of the second electrode in a checkerboard pattern, a generation region where power is generated by vibration is increased.

摘要： An electret electrode is constituted by forming a conductive film on a substrate, laminating a first insulating film and a second insulating film alternatively on the conductive film, and then disposing electret films in which a lower surface, an upper surface and a side surface are covered with a third insulating film and a fourth insulating film. Existing of the first insulating film and the second insulating film between the electret films and the conductive film enables an increase in electric field intensity in the film when the same electric charge is retained, while enables an increase in surface charge density (surface potential) when the electric field intensity is the same.

摘要： An electronic component includes a substrate; a piezoelectric material layer supported directly or indirectly by the substrate; a first electrode arranged on a surface of the piezoelectric material layer on an opposite side of the substrate; and a second electrode arranged on a surface of the piezoelectric material layer on the substrate side. The piezoelectric material layer is sandwiched between the first electrode and the second electrode. The first electrode has a smaller surface area than the piezoelectric material layer. A portion where the piezoelectric material layer is exposed from the first electrode includes a portion that is thinner than a thickness of the piezoelectric material layer between the first electrode and the second electrode. Thus, it is possible to configure a resonator with a higher frequency than its ordinary resonance, and it is easy to achieve an adjustment of the resonance frequency of the resonator, as well as improving the yield of the component and enabling the configuration of an electronic component that includes a plurality of resonators of different frequencies.
