Piezoelectric resonator plate and manufacturing method for piezoelectric resonator plate

A piezoelectric resonator plate comprising a vibration portion and a joining portion that are integrally provided in a substrate having a main face formed in a rectangular shape, the vibration portion including a vibration region configured by forming a pair of excitation electrodes, 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 from a non-flowable material and are electrically connected respectively to the excitation electrodes in the pair, and
• the substrate includes a post portion formed convexly at a position where the pair of terminal electrodes is formed, and
• the conductive bumps are formed respectively on an inner side of the pair of terminal electrodes.
