<P>PROBLEM TO BE SOLVED: To provide a piezoelectric device that prevents a solder fillet part from contacting with a lid or a sealing material so as to prevent the occurrence of trouble due to the contact between the solder fillet part and the lid or the sealing material and achieves simplification of a loading process. Ž<P>SOLUTION: The piezoelectric device 10 is composed of a container 11 formed with a recess 15, a sealing material 18 provided on the top face on the side of an opening of the recess 15 at the sidewall part of the container 11, a piezoelectric vibration element 12 loaded inside the recess 15, each electrode 17 for external connection formed on the outside bottom face of the container 11, and a metal lid 13 arranged on the sealing material 18 so as to airtightly seal the inside of the recess 15 by being joined to the sealing material 18. A part of the outside side face of the sidewall part of the container 11, the sealing material 18 exposed outside the piezoelectric device 10, and the surface of the lid 13 are covered by a heat-resistant insulating layer 14 formed of a silicon dioxide or an aluminum oxide.
