Abstract
A piezoelectric oscillator includes a base member; a piezoelectric resonator mounted on an upper surface of the base member; a lid member joined to the upper surface so as to hermetically seal the piezoelectric resonator; an electronic component mounted on a lower surface of the base member; a mounting frame joined to the lower surface so as to surround the electronic component; and a heat conduction path disposed on the base member and/or the mounting frame. The heat conduction path is electrically isolated from both of the piezoelectric resonator and the electronic component in the piezoelectric oscillator and has heat conductivity. The heat conduction path includes a first heat conduction portion inside where the base member and the mounting frame overlap, and a second heat conduction portion connected to the first heat conduction portion and disposed outside where the base member and the mounting frame overlap.
