发明名称 Piezoelectric resonator plate and manufacturing method for piezoelectric resonator plate
摘要 In a piezoelectric resonator plate, a substrate having a main face formed in a rectangular shape is provided with a vibration portion and a joining portion that are integrated with each other, the vibration portion including a vibration region configured by forming a pair of excitation electrodes, and the joining portion having formed therein a pair of terminal electrodes that is joined to an external portion. The terminal electrodes in the pair each have a conductive bump formed therein and are electrically connected respectively to the excitation electrodes in the pair. Also, the substrate includes a post portion formed convexly at a position where the pair of terminal electrodes is formed.
