A tuning-fork type piezoelectric resonator plate includes: at least a plurality of leg portions serving as vibrating portions; a bonding portion bonded to the outside, and a base portion from which the leg portions and the bonding portion protrude. The plurality of leg portions protrude from a first end face of the base portion and are provided side-by-side on the first end face. The bonding portion protrude from a second end face located opposite the first end face of the base portion at a position located opposite a center position of the plurality of leg portions in a width direction of the first end face of the base portion. And, at least a base end portion of the bonding portion is used as a bond region that is bonded to the outside.

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.

A piezoelectric resonator device comprises a piezoelectric resonator plate, a base for holding the piezoelectric resonator plate, a lid for hermetically enclosing the piezoelectric resonator plate held on the base, and a support member made of a brittle material for reducing external stress to the piezoelectric resonator plate. The piezoelectric resonator plate is held on the base via a support member. In this case, the base, the piezoelectric resonator plate, and the support member are bonded with each other using a base bonding member and a piezoelectric resonator plate bonding member (connection bumps) by FCB using ultrasonic waves. The base is electrically and mechanically bonded with the support member via the base bonding member in a plurality of areas of the support member using ultrasonic waves. Also, the piezoelectric resonator plate is electrically and mechanically bonded with the support member via the piezoelectric resonator plate bonding member in an area of the piezoelectric resonator plate using ultrasonic waves.

An electrode forming region for providing lead electrodes (65a, 65b) is provided on a crystal resonator plate (2). Opposed side surfaces (67a, 67b) of a substrate (6) are formed and inclined in the same direction with respect to a front major surface (63). Also, an adhesion reinforcing portion (7) for reinforcing adhesion to a conductive adhesive (5) is provided in the electrode forming region for the lead electrodes (65a, 65b). For example, the adhesion reinforcing portion (7) is a notch portion which is cut and formed in the opposed side surfaces (67a, 67b). Thereby, an adhesion strength of the crystal resonator plate (2) and the conductive adhesive (5) is increased.

摘要:
A sealing member of a piezoelectric resonator device is configured to hermetically seal a driving electrode formed on a piezoelectric resonator plate. In the sealing member, a through hole is formed so that an electrode pattern formed on both major surfaces of the substrate is brought into conduction; and a conductive member fills in the through hole. The through hole has a smaller diameter at a portion thereof inside the substrate than at both end portions thereof at the major surfaces of the sealing member. Both end faces of the conductive member have a concave shape with respect to the major surfaces of the substrate of the sealing member.
