Abstract
A piezoelectric oscillator element (,) constituting a piezoelectric transformer is supported by lead frames (,). One of the ends of the lead frame (,) is welded to a primary side electrode (,) at a connection portion (,), and the other end is welded to a land (,). One of the ends of the lead frame (,) is welded to a primary side electrode (,) at a connection portion (,) and the other end is welded to a land (,). One of the ends of the lead frame (,) is welded to a secondary side electrode (,) at a connection portion (,) and the other end is welded to a land (,). The connection portions (,and,) are positioned at a node A of oscillation. Since the electrical and mechanical connection is achieved by the lead frames (,), the structure is simple, the thickness of the oscillator is easily reduced, and the oscillator is easily assembled.
