PROBLEM TO BE SOLVED: To provide a piezoelectric oscillator in which the area occupied for packaging an external circuit board can be reduced, while maintaining oscillation characteristics, such as variable sensitivity. SOLUTION: In a piezoelectric oscillator, a piezoelectric vibrating chip is housed in a recess formed on one principal surface of a rectangular container body, a lid body is fixed with a conductor layer provided in a sidewall apex part of the container body, the piezoelectric vibrating chip within the container body is sealed airtightly, and an integrated circuit element and an electronic element are packaged on another principal surface of the container body. In such a piezoelectric oscillator, a wall body is formed at an edge of the other principal surface of the container, and an electrode terminal for external connection is formed from one lateral side of the container body adjacent to the edge, wherein the wall body is formed, extending over the surface of the continuous wall body.
