Problems solved by technology

In the above-mentioned quartz oscillator, there is a problem that since the mounting terminal fixed to the mounting substrate and the both end supports of the vibrating piece are provided on the long sides of the base, the base is easily deformed due to an external force or a difference in thermal expansion coefficient. effect, and the stress applied to the vibrating piece causes the vibration characteristics to change

Abstract

A resonator device includes a base substrate having a fixation section to be attached to a mounting board and a free end, a resonator element having one end connected to a connection section located on the free end side of the base substrate, and a lid member adapted to airtightly seal the resonator element in a space between the lid member and the base substrate.

Description

Technical field [0001] The present invention relates to a vibration device, an electronic device, an electronic device and a mobile body using the vibration device. Background technique [0002] A quartz oscillator has been proposed as a vibrating device (for example, refer to Patent Document 1) in which a rectangular IC chip and a vibrating reed are mounted on a rectangular base (substrate). In the quartz oscillator described in Patent Document 1, the IC chip is mounted on the base by arranging the connection terminals on the long side of the IC chip and aligning the connection terminals with the short side of the base for connection. In addition, both ends of the vibrating piece are supported on both ends of the long side of the base, and mounting terminals of the base are also provided on both ends of the long side of the base. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2002-176316 [0004] In the above-mentioned structure, when an external force is applied to the...
