    摘要： The piezoelectric device according to the invention is provided with a rectangular crystal piece having driving electrodes on front and back main faces thereof, and a base member having two electrode pads near one short side of the crystal piece. The crystal piece is supported on the base member by first and second support portions near one short side thereof, and by an auxiliary support portion on the other short side thereof. A position of the auxiliary support portion relative to the other short side, where L is a distance between two short sides, and H is a distance from the other short side to a peripheral edge of the auxiliary support portion nearest to the other short side, is set to a position at which the distance H stays in a range of distances in which a maximum tensile stress acting on the auxiliary support portion and a maximum von Mises stress of the crystal piece are respectively within predetermined ranges of stress values. For a better resistance to impact, the position of the auxiliary support portion is set to a position at which a value of (H2+D)/L expressed in percentage is equal to or smaller than 20%, where H2 is a value included in the range of distances H in which these stresses are both maximized.

    摘要： Les broches conductrices (2) traversant une embase support d'un résonateur piézoélectrique sont pliées (3,4) l'une vers l'autre de manière que l'espace restant libre soit légèrement inférieur à l'épaisseur du diapason (8). Le diapason (8) est ensuite inséré entre les broches (2) où il reste maintenu par pincement. La fixation est achevée par dépôt d'une pâte conductrice ou d'un alliage de soudure. De préférence, la partie pliée (5) des broches (2) est écrasée pour former un épanouissement plan (7) sur lequel va s'appuyer le diapason (8).

    摘要： 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.
