Abstract:
1. A piezoelectric vibrator element comprising: a vibrating member that is in a rectangular shape with first through fourth sides, a peripheral portion that is continuously formed at the first through third sides in a peripheral area of the vibrating member, a vibrating portion that is formed at a center area of the vibrating member and that is surrounded by the peripheral portion; a neck portion, a buffering portion and a mount portion that are sequentially connected to the peripheral portion located at the second side of the vibrating portion in a first direction; a slit that is formed in the buffering portion between the mount portion and the neck portion; first notches that are formed at both ends of the mount portion in a second direction perpendicular to the first direction; and second notches that are formed at both ends of the neck portion in the second direction, wherein a first width of the peripheral portion located at the second side in the second direction is narrower than a second width of the buffering portion in the second direction, and a third width of the neck portion defined by the second notches in the second direction is the same as the first width of the peripheral portion located at the second side.
