PURPOSE:To limit the amplitude of a quartz oscillator and to prevent defect of the quartz oscillator, by providing a hollow supporting frame at both ends of the quartz oscillator supported with a supporting wire made of one metallic fine wire. CONSTITUTION:After bonding one end of a supporting wire 2 made of a metallic fine wire with an electrode 3 of a quartz for 1 with bonding member such as solder, the wire is folded in parallel with the electrode 3 and along the center of broadwise direction of the quartz for 1. Another end of the supporting wire 2 is fixed with a conductor 8 formed with a frame of a hollow supporting frame 7 made of ceramic and synthetic resin with solder. Supporting frames 7 and 7' are almost symmetrically arranged to the center of lengthwise direction of the quartz for 1, and they are bonded with a terminal of a board 5 and one end of the supporting frames 7 and 7' with solder. Thus, even if the quartz for 1 is oscillated due to external shock, the amplitude of the quartz for 1 is limited at the inside of the supporting frames 7 and 7'. |
