Abstract
An OCXO according to one or more embodiments may include a core section hermetically encapsulated in a heat insulation package. The core section includes: an oscillation IC; a crystal resonator; and a heater IC. The core section is supported by the package via a core substrate. The OCXO further includes a capacitor as an electronic component for adjustment, which is attached to the package by soldering. The core section is vacuum-sealed in a sealed space of the package, while the capacitor is disposed in a space other than the sealed space.
