摘要： Generating efficiency of a vibration power generating device, which generates power by vibration in the biaxial direction, is improved. The vibration power generating device is provided with: a first substrate (101) and a second substrate (106); a first electrode (104) formed on the first substrate; a fixed structural body (103); elastic structural bodies (102X, 102Y) which connect the first substrate and the fixed structural body with each other; and a second electrode (105) formed on the second substrate. Since the overlapping area of the electrodes is increased by arranging rectangular or square conductor parts (104a) of the first electrode and rectangular or square conductor parts (105a) of the second electrode in a checkerboard pattern, a generation region where power is generated by vibration is increased.

摘要： A first supporting section 30 is provided between a substrate section 40 and a second supporting section 20. The first supporting section 30 is structured by, e.g., a film formed from a material having a higher acoustic impedance than a piezoelectric body 11 and the substrate section 40, or a film formed from a material having a smaller Q value than the piezoelectric body 11 and substrate section 40. By inserting the first supporting section 30, most vibration from the second supporting section 20 toward the substrate section 40 is reflected (arrow a), and also a vibration having been transmitted to the substrate section 40 from the second supporting section 20 is prevented from reflecting at the bottom of the substrate section 40 and then returning in a direction of the vibration section 10 (arrow b).
