ABSTRACT:
A chip-like piezoelectric vibrator component is disclosed. The component includes an axially elongated case made of an insulating material, in which an elongated piezoelectric vibrator element is housed. The piezoelectric vibrator element comprises vibrator electrodes formed on opposite main surfaces of a piezoelectric plate, wherein energy is trapped only in the longitudinal direction, whereby thickness sliding vibration is caused. Conductive terminals or caps are fitted into openings at both ends of the case and these are electrically connected to electrodes extending to both ends of the element. Concavities are formed on the conductive terminals or caps at the inner side of the case so that the element may be positioned and held by the concavities, whereby a spacing is secured between the vibrating electrode portions of the element and the inner wall of the case.
