Application: Peizoelectric element and piezoelectric device (Patent ID: US20230402994A1)

The patent filed by Kyocera Corp describes a piezoelectric element with a specific structure that includes a vibration portion, holding portion, excitation electrodes, mounted electrodes, and wiring electrodes. The vibration main surface and holding main surface are on the same plane, with the holding main surface featuring a fixing portion for contact with an element mounting member. The mounted electrodes are positioned side by side on the fixing portion, with inner side edges of the mounted and wiring electrodes connected in a straight line.

The claims detail the specific configuration and features of the piezoelectric element, such as the quadrangular plan view of the vibration portion, the straight line extension of inner side edges of mounted electrodes, and the connection between excitation and mounted electrodes via wiring electrodes. The element also includes holding side surfaces, a recess in the holding portion, and a hermetically encapsulating lid for use in piezoelectric devices. Additionally, the mounting electrodes are connected to the element mounting member using a conductive adhesive, with part of the adhesive placed in the recess for improved functionality.
