Abstract
An oscillator in which organic substances derived from an active element fixing adhesive do not deposit on an oscillating element and in which when the active element or the oscillating element is damaged, other good parts that are not defective can be reused. In the oscillator, an active element 2 is mounted inside a first container 1 whose upper surface is opened, and not only the opening of the first container 1 is closed by an oscillating unit 3 having an oscillating element 6 incorporated therein, but also the oscillating unit 3 is attached onto the opening of the first container 1, so that second connecting electrodes 11a to 11d of a second container 5 of the oscillating unit 3 are electrically connected to first connecting electrodes 14a to 14d of the first container 1. As a result of this construction, the oscillating element and the active element can be accommodated in separate containers, which not only prevents organic substances derived from an active element fixing adhesive from being deposited on the oscillating element, but also parts that are not defective can be reused only by separating the first container from the second container if the active element or the os…
