Patent ID: 8541928

Claim:
A quartz-crystal device, comprising: a rectangular quartz-crystal plate having a long-edge, a short-edge, a first main surface, and a second main surface; a respective excitation electrode situated on each of the first and second main surfaces of the quartz-crystal plate; a respective conductive pad electrically connected to each excitation electrode and extending to the short-edge of the quartz-crystal plate; a package having a mounting surface, a pair of mounting terminals situated on the mounting surface, and respective connecting electrodes electrically connected to the respective mounting terminals; and respective units of electrically conductive adhesive bonding together the connecting electrodes and respective conductive pads to thereby mount the quartz-crystal plate in the package; wherein a shortest distance between an edge of a unit of electrically conductive adhesive and an opposing edge of the excitation electrode is in a range of 10% to 15% the length of the quartz-crystal plate in the long-edge direction.
