ABSTRACT:
The invention provides a piezoelectric oscillator having a reduced horizontal size and capable of being mounted in a small area. The invention also provides a portable telephone and an electronic device using such a piezoelectric oscillator. The piezoelectric oscillator includes a first package and a second package which are firmly connected to each other such that the second package is located on the first package. An oscillator circuit element is disposed in the first package, and a piezoelectric resonator is disposed in the second package. The first package includes a first lead frame and a second lead frame. End parts of the first lead frame are bent downward such that the bent portions at the lower end are exposed to the outside and serve as the first connection terminals. The second lead frame is placed on the first lead frame. End parts of the second lead frame are bent upward so as to serve as second connection terminals. The first connection terminals described above are used as mounting terminals. The second connection terminals are electrically connected to external terminals of the second package.
