Patent ID: 8093785

Claim:
A piezoelectric resonator comprising: a package having a cavity; a plurality of electrode pads disposed within the cavity; a first bonding section disposed on one of the plurality of electrode pads; a second bonding section disposed on another one of the plurality of electrode pads; and a piezoelectric vibrating element having one end supported by the first bonding section and the second bonding section, the piezoelectric vibrating element having: a first face; a second face mutually opposed to the first face; a first electrode disposed on the first face, the first electrode electrically connecting to the first bonding section; and a second electrode disposed on the second face, the second electrode electrically connecting to the second bonding section; an area of the piezoelectric vibrating element supported by the first bonding section and the second bonding section defining a supported region, an area of the piezoelectric vibrating element that is not supported by the first bonding section or the second bonding section defining a movable region; the first bonding section and the second bonding section including a first compound that has a siloxane bond; and a fluorocarbon resin film being disposed on the movable region, the fluorocarbon resin film preventing adhesion of a second compound that has a siloxane bond, the second compound being generated from the first compound.
